MATERIALS AND METHODS
Mice
Bac-transgenic Rorc(γt)-tTATG mice were generated as described previously (S1). The coding
sequence for tTA, including the stop codon, was inserted into exon 1 of Rorc(γt) in place of
the endogenous ATG translation start codon, on a 200-kb BAC (Invitrogen) carrying at least
70 kb of sequence upstream of the Rorc(γt) translation start site. Rorc(γt)-tTATG mice were
crossed with LC1-Cre mice (S2) and then further crossed with Rosa26-YFP (S3) or Rosa26-
RFP (S4) mice for inducible fate mapping. Mice crossed to Rosa26-RFP reporters were
crossed with BAC-transgenic Rorc(γt)-GfpTG mice described before (S5). CCR6-, Nod1-,
Nod2- and Myd88-deficient mice were described previously (S6, S7). All these mice were
kept in specific pathogen-free conditions. Germfree Rorc(γt)-GfpTG mice were obtained by
aseptic caesarean section followed by the adoption of the caesarean-derived pups by germ-
free foster mothers. Health monitoring tests were performed to verify that the germ-free
colony was also free of parasites and of mouse specific viruses. Colonization of germfree
Rorc(γt)-GfpTG mice with SFB or culturable bacteria was performed as described previously
(S8). All animal experiments were approved by the committee on animal experimentation of
the Institute Pasteur and the French Ministry of Agriculture.
Mouse treatments
Triple transgenic mice were treated with doxycycline (Sigma Aldrich) at 1mg/ml in drinking
water containing 5% Sucrose until analysed. To eradicate the intestinal bacterial flora,
transgenic mice were treated with a cocktail of antibiotics containing 5g/L Streptomycin, 1g/L
Colistin, 1g/L Ampicillin and 2.5% Sucrose (Sigma Aldrich) in the drinking water starting
one day before birth, and until analysis at day 56. To verify the effect of doxycycline itself on
the development of RORγt+ILCs, Rorc(γt)-GfpTG mice were treated with 1mg/ml doxycycline
since one day before birth until analysis at day 42. Antibiotic treatment was renewed every
week. To ablate CD4+ cells, triple transgenic mice were injected i.p. with 50µg of anti-CD4
antibody (GK1.5) or 50µg Rat IgG2b isotype control (both from eBioscience) every two days
between day 7 and day 20 after birth. Mice were analyzed at day 21.

Adoptive transfer of cells
Bone marrow cells isolated from 8 weeks old Rorc(γt)-EgfpTG mice were treated with a
combination of lineage depletion kit (the cocktail of antibodies against CD5 B220 CD11b Gr1
Ter-119 (Miltenyi Biotec) and biotin-conjugated anti-mouse NKp46 (R&D systems) and a
total of 1x106 cells was intravenously injected into C57BL/6 mice irradiated at 1000rad.
5x105 of lineage depleted fetal liver cells were also injected into 600rad irradiated d.0
C57BL/6 neonates. Mice were analyzed after 6 weeks.
Isolation of cells and FACS
To isolate mononuclear cells from the small intestinal lamina propria (SI-LP), intestines from
adult mice were cut open and first incubated in PBS (Ca/Mg free) containing 30mM EDTA
for 30 min at 4oC. Tissues were then washed with PBS (Ca/Mg free) by vigorous shaking
three times. Tissues were subsequently cut into 1mm pieces and incubated at 37oC for 60 min
in DMEM (Gibco) containing 1mg/ml collagenase D (Roche) and 1U/ml DNase 1
(Invitrogen). Every 10 minutes, tissues were washed with warm DMEM and re-incubated
with fresh Collagenase and DNase containing medium. Supernatants obtained in each step
were collected. Fetal or neonatal total intestine were isolated and cut into 1mm pieces, and
then incubated at 37oC for 30 min in DMEM containing 1mg/ml collagenase D and 1U/ml
DNase 1. Remaining intestinal fragments were collected and pressed through a 100-µm mesh,
mixed with the collected supernatants, and resuspended in a 40% Percoll solution (GE
Healthcare). Mononuclear cells were collected from the interphase between 80% and 40%
Percoll solutions after spin at 2,700 rpm for 20 min. To obtain single cells from the lymph
node, the spleen and the liver, organs cut into 5mm pieces were incubated at 37oC for 30 min
in DMEM containing 1mg/ml collagenase D and 1U/ml DNase 1 and then pressed through a
100-µm mesh. To obtain mononuclear cells from the liver, 40-80% percoll cell separation was
performed. Fetal liver and adult bone marrow cells were treated with a lineage depletion kit
(Miltenyi Biotec) and lin+ cells were further gated out during analysis. All cells were first
preincubated with mAb 2.4G2 to block Fcγ receptors, and then washed and incubated with
the indicated mAb conjugates for 40 min in a total volume of 100 μl PBS containing 2mM
EDTA and 2% bovine serum. Cells were analysed on FACSCanto I or FACSCantoⅡ(BD
Biosciences) and Flowjo software (Tristar). Cells were sorted with a FACS Aria (BD
Biosciences). The purity of sorted RORγt+ILCs was 95-98%.

Antibodies
Purified polyclonal anti-GFP, Alexa Fluor 488 conjugated anti-rabbit IgG (H+L) and
Alexa647-conjugated anti-Syrian Hamster were purchased from Invitrogen. Pacific blue-
conjugated anti-CD3 (500A2); PE-conjugated anti-CD117 (2B8), anti-RORγt (AFKJS-9),
anti-LAMP-1 (Integrin α4β7) (DATK32), anti-IL-22 (1H8PWSR) and RatIgG1 isotype control
(eBRG1); PerCP Cy5.5-conjugated anti-CD4 (RM4-5); PE-Cy7-conjugated anti-
CD8α (53−6.7) and Streptavidin; APC-conjugated anti-CD4 (RM4-5), anti-CD127 (A7R34)
and anti-CD11c (N418); Alexa 647 conjugated Streptavidin and anti-IL-17A (eBio17B7);
APC-Alexa Fluor®780 conjugated anti-CD3ε (17A2), anti-CD117 (2B8), and anti-CD45.2
(104) were purchased from e-Bioscience. Biotin-conjugated anti-NKp46 and PE-conjugated
anti-CCR6 (140706) was from R&D systems. Purified anti-CD3 (500A2) was from BD
Biosciences. To eliminate lineage positive cells from total bone marrow cells, the mouse
Lineage Cell Depletion kit (a cocktail of antibodies against CD5, B220, CD11b, Gr1 and Ter-
119) was used together with biotin-conjugated anti-mouse NKp46, followed by Auto-MACS
(Miltenyi Biotec).
Cell culture.
GFP+ or YFP+ ILCs were FACS-sorted from the SI-LP of either Rorc(γt)-EgfpTG or triple
transgenic E.14-16 fetuses, day 0 neonates or 4 weeks-old adult mice. Sorted (1000) cells
were suspended in culture medium (OPTI MEM (GIBCO) containing 10% FCS (LONZA
Verviers Belgium lot#9SB001), β2-mercaptoethanol, ampicilin and streptomycin) and seeded
into ftat bottom 96-well plates coated with OP9 or OP9DL1 stroma cells in the presence of
20ng/ml mouse rIL-7 and 20ng/ml mouse rSCF (PeproTec). In some experiments, mouse rIL-
2 (eBioscience) was added at the concentration of 10ng/ml. After 6 days of culture, ILCs and
stroma cells were dissociated with Cell Dissociation Buffer (GIBCO) and 100-300 ILCs per
well were recovered. CD45.2+ hematopoietic cells were analysed by FACS Canto. E.16
Rorc(γt)-EgfpTG fetal liver cells were treated with a lineage depletion kit (Miltenyi) and FACS
sorted. Sorted (200) GFP+ fetal liver cells were cultured in the same conditions as SI-LP
RORγt+ILCs and 500-800 GFP+ cells were recovered.
Cell stimulation and intracellular staining
To assess intracellular IL-17A expression, cells were stimulated for 3hr in DMEM containing
50 ng/ml Phorbol 12-Myristate 13-Acetate (PMA) and 500ng/ml ionomycin (Sigma-Aldrich).
3
For the last 1.5 hr, 10µg brefeldin A (Sigma-Aldrich) was added to the culture medium. For
intracellular IL-22 staining, cells were stimulated with 40 ng/ml mouse IL-23 (R&D systems)
for 3 hr and in the presence of brefeldin A for the last 1.5 hr. After surface staining of c-kit
(CD117), CD4, NKp46, IL-7Rα(CD127) and CD3ε, cells were fixed with 4% PFA (Sigma-
Aldrich) and permeabilized by 1% saponin (Sigma-Aldrich) and then intracellular anti-IL-
17A or Il-22 were performed as described previously (S5). To detect intracellular RORγt, the
Foxp3-staining buffer set (e-Bioscience) was used for fixation and permeabilization of the
cells.
Chemokine receptor staining
For the surface CCR6 staining, intestinal lamina propria cells were first incubated with 10%
FCS containing DMEM at 37oC for 30 min in the presence of anti-CCR6 antibody, followed
by staining at 4oC against other surface molecules such as c-kit (CD117), CD4, NKp46, IL-
7Rα (CD127) and CD3ε.
Cell proliferation
To measure DNA synthesis during cell proliferation in vivo, 50µL of 2mM EdU (Invitrogen)
solution was injected i.p. into day 3 dox-treated TTG-YFP mice daily between day 7 and day
13 after birth. Incorporation into cells of 5-ethynyl-2'-deoxyuridine (EdU) was detected at day
14 with the Click-iTTM EdU Flow Cytometry Assay Kits-Pacific BlueTM (Invitrogen). To
enhance YFP expression of the fixed cell, anti-GFP and Alexa Fluor 488 anti-Rabbit
(Invitrogen) were used.
RNA isolation and qPCR
To perform gene expression analysis, epithelium-containing cells pellets obtained by 30mM
EDTA incubation of small intestine was immediately frozen in liquid nitrogen. Cell pellets
were treated with TRIZOL regent and total RNA was purified according to the manufacture’s
protocol (Invitrogen). RNA was subjected to DNase I digestion and additional purification
using RNeasy Mini kit (Quiagen). RNA was transcribed into cDNA using Superscipt III
reverse transcriptase (Invitrogen) according to the manufacture’s protocol. Quantitative real
time PCR was performed using RT2 qPCR Primer sets and RT2 SYBR-Green master mix
(SABiosciences) on a PTC-200 thermocycler equipped with a Chromo4 detector (Bio-Rad
Laboratories). Data was analysed using Opticon Monitor software (Bio-Rad Laboratories).
4
CT values were normalized to the mean CT values obtained for the two house keeping genes
Hsp90 and Gapdh. All the primers used in qRT-PCR were purchased from SABiosciences;
Hsp90 (NM_008302), Gapdh (NM_008084), Reg3b (NM_011036) and Reg3g
(NM_011260).

Fig. S2. Distinct labelling efficiencies in fate mapped subsets of RORγt+ ILCs.(A) Cells were isolated from 4 weeks old Rorc(γt)-tTATG mice crossed to LC-1 and R26R-Redfluorescent protein (RFP) mice, as well as to the Rorc(γt)-EgfpTG reporter mice. Histograms showthe RFP labelling efficiencies in LTi4 cells and NKp46+ ILCs through the fate mapping cascade.Data shown are representative of three individual experiments. (B) To assess whether RFPlabelling is stochastic or determined by putative subsets within LTi4 cells, RFP labelled and non-labelled LTi4 cells were flow-sorted from tetra-transgenic mice and cultured on OP9 cells in thepresence of IL-7 and SCF, and analyzed after 6 days. The proportion of cells RFP+ cellsgenerated in vitro from RFP- LTi4 cells was 43% and similar to the proportion of RFP+ cellsamong LTi4 cells in vivo, indicating that labelling is stochastic. Given the 5x lower RFP labellingefficiency in NKp46+ ILCs as compared to LTi4 cells, it is therefore unlikely that NKp46+ ILCsderive from LTi4 cells or a putative subset of LTi4 cells endowed with low RFP labellingefficiency.

Fig. S10. Bone marrow cells generate RORγt+ ILCs1x106 Bone marrow cells from Rorc(γt)-EgfpTG mice were purified witha lineage+ cell depletion kit (Miltenyi Biotec) and adoptively transferredinto irradiated C57BL/6 hosts. Donor-derived RORγt+ ILCs (GFP+) inthe small intestinal lamina propria were analyzed 6 weeks later. Data arerepresentative of three independent mice.

Fig. S11. The relative proportions of RORγt+ ILC subsets is determined by mouse ageThe proportions of small intestinal lamina propria LTi4 and NKp46+ ILCs was determined inthe progeny of fetal (E16), perinatal (day 3), pre-weaned (d14), adult (day 28) or total RORγt+ ILCs in triple transgenic mice not treated with dox, and analyzed at E16, day 3, day 14 andday 56. It is concluded that the relative proportions of the RORγt+ ILC subsets is determinedby mouse age, and not by the age of the cells. Error bars, s.d.; n.s, statistically not significantby students’ t-test.

Fig. S12. Doxycyclin affects the generation of Th17 cells, but not of RORγt+ILCs.Oral treatment of Rorc(γt)-GfpTG mice with 1mg/ml doxycycline from birth until 6 weeks ofage effectively affects the bacterial symbiotic microbiota and thereby prevents the generationof Th17 cells (top panel), but has no impact on the subsets of RORγt+ ILCs (middle and lowerpanels) residing in the small intestinal lamina propria. Numbers of Th17 cells are indicated asGFP (RORγt)+ cells in CD4+ T cells. The data shown in dot plots and histograms arerepresentative or a compilation of results obtained in 4 individual mice. Error bars, s.d.; *P <0.05, n.s, statistically not significant, unpaired t-test.
