WebApr 11, 2024 · We established an isogeneic cell model consisting of parental dermal fibroblasts, fibroblast-like iPSC-derivatives (iPS-fibro) and iPS-fibro lacking beta-2-microglobulin (B2M). Using the cells obtained from two patients, we analyzed the activation of autologous and allogeneic T-lymphocytes and NK-cells co-cultured with target cells. … WebHuman iPSC-derived Cardiomyocytes were washed once with PBS (-/-) and were treated with a mixture of Liberase (2.5 mg or 13 units/mL) and TrypLE solution (50:1) for 15 min at 37°C. The solution was neutralized with cardiac differentiation media (CDM).
