PFN1 and integrin‐β1/mTOR axis involvement in cornea differentiation of fibroblast limbal stem cells
2019
Abstract Ex vivo limbal stem cell transplantation is the main therapeutic approach to address a complete and functional re‐epithelialization in corneal blindness, the second most common eye disorder. Although important key points were defined, the molecular mechanisms involved in the epithelial phenotype determination are unclear. Our previous studies have demonstrated the pluripotency and immune‐modulatory of fibroblast limbal stem cells (f‐LSCs), isolated from the corneal limbus. We defined a proteomic profile especially enriched in wound healing and cytoskeleton‐remodelling proteins, including Profilin‐1 (PFN1). In this study we postulate that pfn‐1 knock down promotes epithelial lineage…
Complex and Differential Cytokeratin Profiles in Thymomas and Correlation with Normal Thymus
1997
Cytokeratins (CKs) are characterized by highly diverse expression patterns and thus serve as potent epithelial differentiation markers. We have studied 31 cases of thymomas (12 cortical, 2 predominantly cortical, 5 mixed, and 9 medullary type thymomas as well as 3 well-differentiated thymic carcinomas) and, for comparison, 15 normal thymi, for the presence of different CK polypeptides. Immunohistochemistry was performed on cryostat sections using the indirect immunoperoxidase method.
