Pannexin 3 Regulates Skin Development via Epiprofin

The authors demonstrated that Pannexin 3 (Panx3) regulated skin development by modulating the transcription factor, Epiprofin (Epfn). In cell culture, Panx3 overexpression promoted HaCaT cell differentiation, cell cycle exit and enhanced Epfn expression.

Cationic Cross-Linked Nanocellulose-Based Matrices for the Growth and Recovery of Intestinal Organoids

Cellulosic matrices were cross-linked with Ca2+ and Mg2+ and intestinal organoids cultured for four days. The organoids were recovered for passaging and RNA extraction. TEMPO-periodate-oxidized nanocellulose fibers formed functionalized hydrogels and supported the growth of intestinal organoids.

Locally Applied Stem Cell Exosome-Scaffold Attenuates Nerve Injury-Induced Pain in Rats

Researchers developed an alginate scaffold with human umbilical cord mesenchymal stem cell exosomes to treat nerve injury-induced pain. In vitro studies of PC12 and HEK293 cells were used to evaluate the neuroprotective and neurotrophic effects of exosomes.

Unconventional Secretion of PKCδ Exerts Tumorigenic Function via Stimulation of ERK1/2 Signaling in Liver Cancer

Scientists showed that PKCδ is a secretory protein that regulated cell growth of liver cancer. Full-length PKCδ was secreted to the extracellular space in living liver cancer cells under normal cell culture conditions and in xenograft mouse models.
