However, their functionality and therapeutic potential are intricately modulated by interactions with immune cells, particularly macrophages and microglia. Microglia, as CNS-resident macrophages, are distinct from peripheral macrophages in their roles and characteristics, contributing to specialized functions within the CNS. Recent evidence suggests that microglia, as CNS-resident macrophages, contribute to the quality assurance of NSPCs by eliminating stressed or dysfunctional cells, yet the mechanisms underlying this process remain largely unexplored. Furthermore, macrophage polarization states, such as M1 and M2, appear to differentially influence NSPC quality, potentially impacting neurogenesis and regenerative outcomes. Identifying surface markers indicative of NSPC stress could provide a strategy for selecting optimal cells for transplantation therapies. Additionally, <em>in vivo</em> clonal labeling approaches may enable precise tracking of NSPC fate and their interactions with immune cells. Beyond macrophages and microglia, the roles of other immune cells, including T cells and neutrophils, particularly in injury and neurodegenerative disease contexts, in the context of CNS injury and disease are emerging areas of interest.

Under-expression of miR-99a-5p stimulated BM-MSCs transition into GC-MSCs-like cells, while overexpression of this miRNA abrogated tumor-promoting roles of GC-MSCs. miR-99a-5p not only targeted modulation of fibroblast growth factor receptor (FGFR3) but also negatively affected its phosphorylated levels. Suppression of FGFR3 signaling by AZD4547 or siRNA against FGFR3 notably blocked the miR-99a-5p inhibitor-induced BM-MSCs transition and the oncogenic roles of GC-MSCs. However, miR-99a-5p overexpression did not diminish the ability of gastric cancer cells to educate BM-MSCs. The levels of phosphorylated FGFR3, but not total FGFR3, was increased in BM-MSCs educated by gastric cancer cells. AZD4547 significantly suppressed the education capacity of gastric cancer cells on BM-MSCs. Taken together, although manipulating miR-99a-5p to mimic its levels in GC-MSCs promotes the transition of BM-MSCs into GC-MSCs-like cells, FGFR3 signaling, rather than miR-99a-5p, is unexpectedly essential for the education of BM-MSCs by gastric cancer cells.

Our lab has identified that the cyclooxygenase (COX-1 and COX-2) isoenzymes are expressed during the early stages of vertebrate embryonic development, and that global inhibition of COX-1 and COX-2 function disrupts NC cell migration and differentiation in <em>Ambystoma mexicanum</em> (axolotl) embryos. NC cells differentiate into various adult tissues including craniofacial cartilage, bone, and neurons in the peripheral and enteric nervous systems. To investigate the specific phenotypic and molecular effects of NPX exposure on NC development and differentiation, and to identify molecular links between COX inhibition and NC derivative anomalies, we exposed late neurula and early tailbud stage axolotl embryos to various concentrations of NPX and performed immunohistochemistry (IHC) for markers of migratory and differentiating NC cells. Our results reveal that NPX exposure impairs the migration of SOX9+ NC cells, leading to abnormal development of craniofacial cartilage structures, including Meckel’s cartilage in the jaw.

Interestingly, these enzymes can also play less expected roles in cell survival, polarity and motility via other substrates (e.g. receptors, chemokines), through an intracellular localization (e.g. the nucleus) or via non-catalytic functions. Most of these unconventional functions are yet to be functionally validated in a physiological context. Here, we used the delamination of the cephalic Neural Crest (NC) cells of the chicken embryo, a well described experimental model of epithelial-mesenchymal transition (EMT), to study the <em>in vivo</em> function of MMP14 (a.k.a MT1-MMP). MMP14 is a transmembrane MMP known for its importance in cell invasion and often associated with poor prognosis in cancer. We found that MMP14 is expressed and required for cephalic NC delamination. More specifically, MMP14 is necessary for the downregulation of Cadherin-6B and a co-inhibition of Cadherin-6B and MMP14 expressions is sufficient to restore NC delamination. Cadherin-6B is normally repressed by Snail2. Surprisingly, in MMP14 knockdown this lack of Cadherin-6B repression occurs in the context of a normal expression and nuclear import of Snail2. We further show that MMP14 is not detected in the nucleus and that Snail2 and MMP14 do not physically interact. These data reveals that a yet to be identified MMP14-dependent signaling event is required for the Snail2-dependent repression of Cadherin-6B. In conclusion, this work provides an <em>in vivo</em> example of atypical regulation of Cadherins by an MMP which emphasizes the importance and diversity of non-canonical functions of MMPs.</div></div>","PeriodicalId":50579,"journal":{"name":"Differentiation","volume":"142 ","pages":"Article 100836"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, cartilage is incapable of self-repair and any damage leads to degradation in osteoarthritis (OA). Autologous chondrocyte implantation therapies are currently being used to treat focal cartilage defects caused by post-traumatic OA (PTOA). For chondrocyte implantation, chondrocytes are isolated from healthy regions of cartilage from damaged joints, expanded on stiff polystyrene to increase cell number, and reimplanted into damaged areas to stimulate repair. Unfortunately, chondrocyte implantations can ultimately fail as chondrocytes dedifferentiate during expansion. In dedifferentiation, chondrocytes increase in size, elongate, and express contractile cytoskeletal molecules. Furthermore, cells produce a fibroblastic matrix which is biomechanically inferior to articular cartilage matrix. Therefore, developing a greater understanding of dedifferentiation is imperative. In the dedifferentiation process, cellular actin filaments reorganize from a cortical organization into stress fibers. The formation of stress fibers plays a crucial role in chondrocyte dedifferentiation by regulating chondrocyte cell morphology and gene expression. Determining the actin-based molecular underpinnings in chondrocyte dedifferentiation may enable the specific targeting of stress fibers to promote redifferentiation of passaged cells and improve chondrocyte implantation outcomes. This review focuses on how targeting regulators of actin filament organization may promote the redifferentiation of expanded chondrocytes for implantation, thus increasing potential therapeuticlongevity.</div></div>","PeriodicalId":50579,"journal":{"name":"Differentiation","volume":"143 ","pages":"Article 100847"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
