Potassium Current Signature of Neuronal/Glial Progenitors in Amniotic Fluid Stem Cells.
Cells
January 2025
Department of Chemistry, Biology and Biotechnologies, University of Perugia, Via dell'Elce di Sotto 8, 06123 Perugia, Italy.
Article Synopsis
- Amniotic fluid contains stem cells (AF-SCs) that have potential uses in regenerative medicine for treating various injuries and diseases.
- When exposed to basic Fibroblast Growth Factor (bFGF), AF-SCs show the ability to survive and migrate in a rat brain model, resembling characteristics of neuronal/glial progenitor cells.
- The study employs electrophysiological techniques to identify specific potassium currents in AF-SCs and confirms that histamine can influence calcium dynamics and potassium current activation in these cells.

Objective We evaluated the outcomes of tympanic membrane regenerative treatment using gelatin sponge, recombinant basic fibroblast growth factor (bFGF), and fibrin glue at Yokosuka Kyosai Hospital. Methodology We enrolled a total of 42 patients with tympanic membrane perforations (TMPs) (44 ears; right:left = 21:23) that were treated using gelatin sponge, recombinant bFGF, and fibrin glue between July 2020 and December 2023 at Yokosuka Kyosai Hospital. TMP closure rates, improvement of hearing level, and complications were retrospectively included in the evaluation items.

The risks associated with wound infections are significant, making a snug-fitting hydrogel dressing an optimal choice for wound management. For it, we employed the self-cross-linking method of oxidized sodium alginate (SCSA), incorporating clarithromycin (Cla) and basic fibroblast growth factor (bFGF) to formulate a rapidly forming, bacteriostatic, and wound-healing hydrogel (SCSA@C/b). Bacteriostatic and cytocompatibility assays demonstrated that SCSA@C/b exhibits exceptional antibacterial activity alongside strong biocompatibility.

Objective To investigate the effect of serum containing Xinfeng capsule (XFC) on the angiogenesis of human umbilical vein endothelial cells (HUVEC) induced by rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) and its mechanism of action. Methods An in vitro co-culture model of RA-FLS and HUVEC was established. Serum containing XFC was prepared by oral gavage of SD rats.

Article Synopsis
- A 68-year-old male experienced irritation in both eyes, including symptoms like photophobia and tearing, after starting dupilumab for severe atopic dermatitis.
- He had a specific corneal ulcer in the right eye and a pannus in the left eye, but tests ruled out infections.
- Treatment with eye drops led to significant improvement, and follow-up revealed healing of the corneal lesions and improved vision.
