Bone marrow-mesenchymal stem cells alleviate microglial Pyroptosis after intracerebral hemorrhage in rat by secreting C1q/tumor necrosis factor-related protein 3
CONCLUSION: BMSCs can inhibit neuroinflammation by inhibiting microglial pyroptosis, thus alleviate ICH symptoms, likely by suppressing the Syk signaling pathway while promoting the PI3K/AKT signaling pathway activation through producing CTRP3.PMID:36958593 | DOI:10.1016/j.expneurol.2023.114387

A Mesenchymal stem cell line (B10) increases angiogenesis in a rat MCAO model.
Abstract A human mesenchymal stem cell line (B10) transplantation has been shown to improve ischemia-induced neurological deficits in animal stroke models. To understand the underlying mechanism, we have investigated the effects of B10 transplantation on cerebral angiogenesis in a rat middle cerebral artery occlusion (MCAO) model. B10 cells were transplanted intravenously 24 h after MCAO. Immunofluorescence staining results showed that compared to PBS-groups, vWF positive vessel and endoglin positive new vessels were increased in B10-transplanted MCAO groups in the lesion areas. The mRNA of angiogenesis factors ...

Glial cell line-derived neurotrophic factor promotes increased phenotypic marker expression in femoral sensory and motor-derived Schwann cell cultures.
In this study, SCs harvested from the sensory and motor branches of rat femoral nerve were expanded in vitro and then cultured with 50 or 100ng/mL of GDNF. The exogenous GDNF promoted differentiation of sensory and motor-derived SCs back to their native phenotypes, as demonstrated by decreased proliferation after 7days and increased expression of S100Ββ and phenotype-specific markers. Furthermore, inhibiting Fyn with Src family kinase inhibitors, PP2 and SU6656, and siRNA-mediated knockdown of Fyn reduced GDNF-stimulated differentiation of sensory and motor-derived SCs. These results demonstrate that activating Fyn is ne...
