Established Yazd Human Foreskin Fibroblast Lines (#8, #17, and #18) Displaying Similar Characteristics To Mesenchymal Stromal Cells: A Lab Resources Report

Background: fibroblasts from different parts of the human body have been used in cell biology, drug discovery and cell therapy studies. one of the most available sources of human fibroblasts is neonatal foreskin. not only do these cells have woundhealing applications, but they are also the most popular source for pluripotent stem cell biotechnology. moreover, several studies have indicated that different sources of fibroblasts display similar features to mesenchymal stem cells. objective: generation and establishment of new human foreskin fibroblast cell lines called yazd human foreskin fibroblasts (yhffs). materials and methods: in this lab resources study, the production of 3 yhff cell lines (yhff#8, yhff#17, and yhff#18) is reported. their biological features were characterized using immunofluorescence, polymerase chain reaction, and flowcytometry for mesenchymal markers such as fibronectin, vimentin, cd44, cd73, cd90, cd105, and hematopoietic markers cd34 and cd45. results: the yhff cell lines were passaged more than 40 times and their normal karyotype was checked using g-binding. similarly to previous reports, the flow cytometry analysis revealed that the yhff cell lines displayed mesenchymal stromal cell characteristics. conclusion: this study will contribute to the development of clinical-grade cell-based products such as micro-vesicles and exosomes for future therapeutic applications in regenerative medicine.
