![عکس صفحه اول مقاله: Endothelial differentiation of canine yolk sac cells transduced with VEGF Endothelial differentiation of canine yolk sac cells transduced with VEGF](/preview/png/5794527.png)
- We established a primary cell culture from yolk sac cells derived from dog fetuses.
- The cells from yolk sac are easy to isolate, grow and transduce.
- Yolk sac cells showed mesenchymal and endothelial marker expression.
- These cells present potential to differentiate in another cell lines.
Yolk sac (YS) is the site of blood-cell production where primitive erythroid cells originate and complete their maturation. YS is a source of precursor cells, however its differentiation potential and suitability for cell therapies are not well described. YS can be a cell source when neovascularization is required. This study characterized YS canine cells, transduced with VEGF, to analyze then using Immunocytochemistry, flow cytometry and real time PCR. Immunocytochemistry: positive expression for CD105, PCNA, VEGF and vWF, flow cytometry for CD105, VEGF, PCNA, OCT-4 and RT-qPCR for VEGF, CD31, CD105, PCNA and FLT - 1, indicating that these cells have characteristics of endothelial progenitor and pluripotency. After transduction,the YS cells changed their morphology and showed endothelial-like cells. We suggest, because of their cell surface phenotype as well as their capacity to differentiate into endothelial-like cells, that canine YS represents a source of cells for neovascularization therapies.
