Subcluster 3 cells are part of the follicle cell lineage because they express gsdf (Figure 4AC), yet these cells also express many genes that are unique to this subpopulation, arguing that they are distinct from the stage IB and II follicle cells identified above. This analysis also revealed that lhx9+ cells appear to surround these early-stage germ cells (Figure 4F and F). j, Median number of cells per subject by cell type. d, Distribution of the concentration of ChE species from c) (p-value=0.046, Wilcoxon rank-sum test, two-sided).

Identification of putative regulatory regions and transcription factors associated with intramuscular fat content traits. As to the point about the definition of early germ cells, we have better defined what germ cell-stage the various marker genes identify when these markers are first introduced in the germ cell section (page 7, lines 12-15). Proc. (e) Distribution of cis-eQTLs around TSS (1Mb up- and down-stream) in adipose. Additionally, there is significant expression of wnt8a (Kelly et al., 1995) in oocytes, wnt9a in stromal cells, wnt9b (Crotwell and Mabee, 2007) in follicle cells, and wnt11 (Makita et al., 1998) in stromal and theca cells (Figure 5figure supplement 1). A discussion of these previous results have been added to the manuscript (Page 24, Lines 17-26). Single-cell RNA sequencing libraries were prepared by the UC Davis DNA Technologies core. Excellent point. Tcw, J. et al. Correspondence to Supplementary Table 15. These results show that follicle cells expressing gja11 are restricted to stage II follicles (Figure 4E). Neurosci. Unadjusted wilcoxon test p-values shown, two-sided (N=6 per group, except for APOE4/4, where N=8). (a) cis-eQTLs discovered in monocytes, and mammary gland show enrichments for top SNPs (top 10%) associated with age at first calving (AFC) (P=0.001, the two-sided permutation test with 1,000 times), and somatic cell score (SCS) (P=0.001, the two-sided permutation test with 1,000 times) respectively, compared to the null expectation (shown in gray) defined by Not eQTLs. The cell suspension was then added to 25 ml of L15 in a 50 ml conical tube to dilute the trypsin and centrifuged for 3 min at 300 g. The cell pellet was resuspended and washed two times with 5 ml of L15 using a P1000 pipette and centrifuged for 3 min at 300 g. The cell pellet was then resuspended and filtered as described above.

Reviewer #3 (Recommendations for the authors): Text page 13, line 30, "Remarkably, we found that early-stage germ cells were always contacting lhx9+ pre-follicle cells". To explore the relationship between the lateral and medial edges of the juvenile ovary and the germinal zone in the adult ovary, we performed HCR RNA-FISH for stm on transverse sections from 3-month-old adult ovaries. The shaded area around the lines represents the 95% confidence interval for the fitted values (the lines). Cell Stem Cell 17, 360372 (2015). Profile and regulation of apolipoprotein E (ApoE) expression in the CNS in mice with targeting of green fluorescent protein gene to the ApoE locus. For example, lhx9 appeared to have higher expression in cells distal to the subcluster 1 in the UMAP while gsdf and bone morphogenetic protein 6 (bmp6; Smith et al., 2006) appeared higher in cells proximal to subcluster 1 (Figure 4A and C). In addition, and importantly, all of the markers we used to identify our cell populations were identified as markers of these cell types prior to scRNA-seq technology.

Article To genetically manipulate glycolytic flux and FBP levels, we generated a mouse model enabling the conditional overexpression of dominant active, cytoplasmic PFKFB3 (cytoPFKFB3). P2l6 Would be helpful to the reader to have the new genes that are KOd listed in the abstract and will make the paper easier to find in an online search. We have not localized the StAR expressing cells so we do not know if they are differentially localized to particular stage follicles. Asterisks identify autoflorescent red blood cells. We found that the majority of genes detected in follicle cells are expressed uniformly throughout the cluster (e.g., gsdf, foxl2a/b, and amh; Figure 4A and B, Figure 4figure supplement 1). All references to smFISH have been changed to HRC RNA-FISH.. Castellano, J. M. et al. 21, 285 (2020). Importantly, this reference dataset will facilitate the use of zebrafish to study female reproductive diseases and disorders of sexual development. Known stromal cell types include interstitial cells, which are collagen-producing connective tissue (fibroblast) that provide structure integrity to the ovary, surface epithelial cells that surround the ovary, vasculature and associated perivascular cells, and resident blood cell types (Kinnear et al., 2020). Prior to imaging, sections were stained 1 hr with 1 g/ml 4,6-diamidino-2-phenylindole (DAPI) in PBS, cleared in glycerol-PBS gradient (30, 50, and 70%) for 10 min each, and then mounted with ProLong Diamond Antifade Mountant.

You are correct that cxcr4b=odysseus, not cxcr4a. Have the authors tested for the expression of particular genes in sub-cluster 3 of the stromal cells and not found it or just not tested? UMAP was used for dimensionality reduction. This niche is crucial for maintaining most GSCs in an undifferentiated state while also allowing some to differentiate. Front.

We assigned these clusters provisional cell-type identities using the expression of known cell type-specific genes as follows: germ cells deadbox helicase 4 (ddx4; formerly vasa; Yoon et al., 1997); follicle cells gonadal soma derived factor (gsdf; Gautier et al., 2011); theca cells cytochrome P450 cholesterol side-chain cleaving enzyme (cyp11a2; Parajes et al., 2013); vasculature Fli-1 proto-oncogene (fli1a; Brown et al., 2000); neutrophils myeloid-specific peroxidase (mpx; Lieschke et al., 2001); macrophages macrophage-expressed gene 1 (mpeg1.1; Zakrzewska et al., 2010); NK cells NK-lysin tandem duplicate 2 (nkl.2; Carmona et al., 2017; Tang et al., 2017; Figure 1, Figure 1figure supplement 3B). Theca cells are found around and between oocytes but are otherwise not well characterized in zebrafish. P values were calculated using one-way ANOVA with Bonferroni correction. These cells were likely late oocyte progenitors, including those that are undergoing premeiotic S-phase (Figure 2GI). Zebrafish used for scRNAseq libraries are Tg(piwil1:egfp)uc02 transgenics (formerly ziwi:egfp; Leu and Draper, 2010) in the AB strain.

At 5 dpf, zebrafish larvae are placed into 1 l aquaria containing 250 ml 4 parts per thousand (ppt) seawater (Crystal Sea), at no more than 30 fish/tank. Pathway choice is therefore not dictated solely by the expression of Cyp19a1a, but instead by the presence or absence of the two additional enzymes encoded by 17-hydroxysteroid dehydrogenase types 1 and 3, called Hsd17b1 and Hsd17b3. Barbeira, A. N. et al. Cells expressing the indicated gene are colored purple, and the relative intensity indicates relative expression levels (intensity scale for each plot is on the right). Excellent suggestion These have been added. Aibar, S. et al. WebMultiple tools are available for transcriptome assembly, however, no single tool can provide the best assembly for all datasets. In addition to producing mature gametes, the other major role of the ovary is to produce the sex steroid hormone 17-estradiol (E2), which induces female-specific sex characteristics throughout the body. These mechanisms are only active during an early larval critical period for structural plasticity. PubMed (B) Schematic of the wnt9b genomic locus.
