1/2 chameleon & human embryos exhibit an epiblast lumen before #gastrulation initiates. However, they reach this stage via different mechanisms. Our new study @natcomms.nature.com explores early development & lumenogenesis in the veiled chameleon. #evodevo #devbio www.nature.com/articles/s41...

Epiblast lumenogenesis is not a mammalian-specific trait - Nature Communications

Weberling et al. characterise veiled chameleon pre-oviposition development from fertilisation to the initiation of gastrulation and show that pre-gastrulation lumenogenesis occurs via a purse string m...

Thrilled that our paper on anole oogenesis & germinal bed morphology is now published following peer review. Mammals & birds have finite egg cells - squamates however have a stem cell niche within the ovary - the germinal bed. Such a great collaboration with co-first author @holyanole.bsky.social

Through confocal imaging we describe basement membrane deposition in the ovary during folliculogenesis. We can report a double basement membrane deposited on either side of the granulosa cell layer surrounding the follicles.

Exploring the sub-cellular architecture of the germinal bed & stage II follicles, we could analyse the granulosa (g) and theca (th) cell layers surrounding stage II follicles. Primordial follicles (pf) start exhibiting enlarged nuclei and cytoplasm!

Oogenesis takes place in 10 stages. It starts in the oogonial nest - a mitotic stem cell niche within the germinal bed - which then undergo meiosis to form primordial follicles We identified oogonia and primordial follicles using section H&E staining paired with confocal DAPI/WGA staining!

Thrilled that our preprint on anole oocyte formation is now online @holyanole.bsky.social ! Such a great collaboration merging our expertise in anole reproductive tract morphology and early embryogenesis to understand how egg cells form!

Bonnie Kircher@holyanole.bsky.social · 11mo ago

@a-weberling.bsky.social & I characterize oogenesis from initiation in the germinal bed to ovulatory follicles for the first time in the brown anole, a powerful reptile model for evo-devo & functional genetics! Full preprint here: www.biorxiv.org/content/10.1...
