Multi-agent-based computational modeling of #Lumenogenesis from a single proliferating cell
High Matrix density & dynamic viscosity->
Formation of multiluminal structure instead of a single cyst lumen
This is a very easy-to-read computational modeling paper (minimal math requirement😁)
Cell cycle/polarity/secretion
Cell-cell (attractive+repulsive) + cell-fluid interaction (repulsive) + cell-matrix interactions
Geometry & Biomechanics (but not biochemical property of matrix)

Kidney epithelial #Tubuloid
CD24+ epithelial progenitor-derived
4-phase protocol, Matrigel +Wnt3a/RSPO1, grow > 6 mo
CRISPR modeling #ADPKD, Cyst size responsive to #Tolvaptan
Super-impressive single-cell or single-nuclei RNAseq analyses to dissect the spatiotemporal molecular/cellular dynamics of this cool renal tubuloid, laying a critical foundation to enhance its clinical utilities👍
Wonderful #Lumenogenesis of CD24+ epithelial progenitor-derived nephrospheres, day 7 in Matrigel🤠

Pancreatic Rab11a/Rab11b dKO->
Aberrant polarized transport of apical/basolateral proteins->
AMIS supernumerary->
Defects in ductal #Lumenogenesis; Acinar morphogenesis; Pancreatic cell lineage dysregulation
Highly intriguing, PancRab11KO->⏬Sox9+ bipotent progenitor & #Islet mass-> #GlucoseIntolerance in suvived adult🐭
Lumenized epithelial paracrine or endocrine-autonomous defect?😆
No baseline change in fast glucose. Insulin/glucagon? Adult islet histology-Amyloid degeneration?
The branched, lumenized pancreatic duct is fragmented into disconnected Microlumens + enlarged Cyst in PancRab11KO🐭
Can't help but think Rab35 in anisotropic Lumenogenesis of liver #BileCanaliculi
Is there a primary hydro-osmotic defect here?😋
Still, what happens to pancreatic vascular morphogenesis in Panc-Rab11 KO🐭?(Surely, epithelia & endothelia are coupled🤪)
More importantly, now it's the magic timing if you also want to have such amazing stories
