PDL stem cells (PDLSCs) contained in the PDL can differentiate into cementoblasts, osteoblasts, and PDL fibroblasts, with essential roles in periodontal tissue regeneration. Therefore, PDLSCs are expected to be useful in periodontal tissue regeneration therapy. In a previous study, we differentiated induced pluripotent stem cells (iPSCs) into PDLSC-like cells (iPDLSCs), which expressed PDL-related markers and mesenchymal stem cell (MSC) markers; they also exhibited high proliferation and multipotency. However, the iPSCs used in this differentiation method were cultured on mouse embryonic fibroblasts; thus, they constituted on-feeder iPSCs (OF-iPSCs). Considering the risk of contamination with feeder cell-derived components, iPDLSCs differentiated from OF-iPSCs (ie, OF-iPDLSCs) are unsuitable for clinical applications. In this study, we aimed to obtain PDLSC-like cells from feeder-free iPSCs (FF-iPSCs) using OF-iPDLSC differentiation method. First, we differentiated FF-iPSCs into neural crest cell-like cells (FF-iNCCs) and confirmed that FF-iNCCs expressed NCC markers (eg, Nestin and p75NTR). Then, we cultured FF-iNCCs on human primary PDL cell-derived extracellular matrix for 2 weeks; the resulting cells were named FF-iPDLSCs. FF-iPDLSCs exhibited higher expression of PDL-related and MSC markers compared with OF-iPDLSCs. FF-iPDLSCs also demonstrated proliferation and multipotency in vitro. Finally, we analyzed the ability of FF-iPDLSCs to form periodontal tissue in vivo upon subcutaneous transplantation with β-tricalcium phosphate scaffolds into dorsal tissues of immunodeficient mice. Eight weeks after transplantation, FF-iPDLSCs had formed osteocalcin-positive bone/cementum-like tissues and collagen 1-positive PDL-like fibers. These results suggested that we successfully obtained PDLSC-like cells from FF-iPSCs. Our findings will contribute to the development of novel periodontal regeneration therapies.</p>","PeriodicalId":94214,"journal":{"name":"Stem cells and development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clarifying the role of STC2 in NSPCs is essential for devising novel strategies to enhance the intrinsic potential for brain regeneration postinjury. Our study revealed the expression of STC2 in NSPCs derived from the SVZ of the C57BL/6N mouse. In cultured SVZ-derived NSPCs, STC2 treatment significantly increased the number of Tuj1 and DCX-positive cells. Furthermore, STC2 injection into the lateral ventricle promoted the neuronal differentiation of NSPCs and migration to the olfactory bulb. Conversely, the STC2 knockdown produced the opposite effect. Further investigation showed that STC2 treatment enhanced AKT phosphorylation in cultured NSPCs, whereas STC2 inhibition hindered AKT activation. Notably, the neuronal differentiation induced by STC2 was blocked by the AKT inhibitor GSK690693, whereas the AKT activator SC79 reversed the impact of STC2 knockdown on neuronal differentiation.

Two isogenic hiPSC lines were generated through CRISPR/Cas9: a CHM knock-out line from a healthy donor and a corrected CHM patient line using a knock-in approach. The differentiated hiPSC-RPE lines exhibited critical morphological and physiological characteristics of native RPE, including the presence of the tight junction markers Claudin-19 and Zonula Occludens-1, phagocytosis of photoreceptor outer segments, pigmentation, a postmitotic state, and the characteristic polygonal shape.
