Induction of menstruation in mice reveals the regulation of menstrual shedding During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉
@karalmckinley.bsky.social
We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

This is just a small piece of a big Timelapse made by a very talented PhD student in the @beckergroup.bsky.social . Credit: @ozuozge.bsky.social . Hopefully something will come soon thanks to it.

Zebrafish larvae are really good for time lapses. Just take some popcorns enjoy them like if they were movies. Here you can see with your own eyes how immune cells divide. This one I call it "Divide and flee" #spinalcordregeneration #zebrafish #timelapse #microglia

Our work on the TET enzymes in retinal development is out. We identified that rod fate is inhibited when DNA demethylation is prevented by removal of the TET enzymes. Interestingly, photoreceptor numbers are normal. We utilized WGBS and bACE-seq to profile the precise localization of 5mC and 5hmC,…

Progenitor heterogeneity in the developing telencephalon. A multi-panelled figure showing different progenitor cells in different areas of the developing telencephalon of the killifish. HCR-FISH targeting CX43 (pan Astro-RG, magenta) and ZIC2 (NE-RG, yellow) (A) or NGPmix (turquoise) (B), is combined with immunohistochemical staining for the proliferation marker PCNA (white). NGPs account for the bulk of proliferation; Astro-RGs and NE-RGs appear both dividing and non-dividing depending on the location in the telencephalon. (C-E) Magnifications of the regions in the boxes in A and B. Non-dividing Astro-RGs (CX43+, PCNA−) are indicated with a magenta arrowhead and appear isolated in between stretches of dividing NGPs. (F) Illustration of a 5 dph coronal telencephalic section at mid-anterior-posterior level. The distribution of dividing and non-dividing Astro-RGs, NE-RGs and NGPs is displayed in the ventricular zone.

African turquoise killifish are short-lived & their CNS exhibits human-like ageing. Zandecki @eveseuntjens.bsky.social & co reveal the cellular diversity during the explosive growth of the telencephalon, uncovering specific progenitor signatures for each neurogenic region. 🧠 doi.org/10.1242/bio....

Absence of a prolonged macrophage and B cell response inhibits heart regeneration in the Mexican cavefish A balanced immune response after cardiac injury is crucial to successful heart regeneration, but knowledge of what distinguishes a regenerative from a scarring response is still limited. The Mexican c...

It has been known for a long time that if the starting point of limb regeneration is at the hand level or close to the shoulder, it would take about the same time to regenerate. Puzzling right?
