|Abstract:||The culture of human corneal endothelial cells (CECs) is critical for the development of suitable graft alternative on biodegradable material, specifically for endothelial keratoplasty, which can potentially alleviate the global shortage of transplant-grade donor corneas available. However, the propagation of slow proliferative CECs in vitro can be hindered by rapid growing stromal corneal fibroblasts (CSFs) that may be coisolated in some cases. The purpose of this study was to evaluate a strategy using magnetic cell separation (MACS) technique to deplete the contaminating CSFs from CEC cultures using antifibroblast magnetic microbeads. Separated labeled and flow-through cell fractions were collected separately, cultured, and morphologically assessed. Cells from the flow-through fraction displayed compact polygonal morphology and expressed Na+/K+ATPase indicative of corneal endothelial cells, whilst cells from the labeled fraction were mostly elongated and fibroblastic. A separation efficacy of 96.88 was observed. Hence, MACS technique can be useful in the depletion of contaminating CSFs from within a culture of CECs. © 2012 Gary S. L. Peh et al.|
