The aim of the study was to produce thermally cross-linked polymer films based on poly(1,5-pentanediol azelate) and poly(1,4-butanediol citrate) with antimicrobial activity for medical applications. Well-formed, cross-linked, flexible materials differing in appearance depending on the conditions of the cross-linking process were obtained. In general, a lower cross-linking temperature was found to promote less brittle and more flexible films with greater structure uniformity. The polymer films had hydrophilic surfaces (water contact angle 40°-60°). All polymer films maintained integrity after immersion in PBS buffer. Most likely, the lower hydrophilicity of the polyazelate phase limited their degradation.

Additionally it facilitated the migration and differentiation of HFSCs, as evidenced by an increased number of hair follicles in HE-stained skin tissues.

In mammals, during progression from pre-implantation to post-implantation stage, pluripotent cells undergo different state transitions characterized by changes in gene expression and development potential. These developmental states include: (i) a naive pluripotency (pre-implantation embryonic stem cells, or ESCs), (ii) an intermediate condition (formative state), and (iii) a primed pluripotency (late post-implantation ESCs derived from epiblasts also named EpiSCs). The transitions are regulated by an interconnected network of pluripotency-related genes. Transcription of genes such as <i>Oct4, Sox2</i>, and <i>Nanog</i> is crucial for obtaining and maintaining pluripotency. These three factors form an autoregulatory loop by binding to each other's promoters to activate their transcription. Other factors play a significant ancillary role in the transcription factor network preserving cell pluripotency. In the review, we will also mention some of the more relevant cytokines, molecules, signaling pathways, and epigenetic modifications that induce and control pluripotency gene expression.
