简介：
Overview
This protocol describes an enhanced method to increase the co-expression of PDX1 and NKX6.1 transcription factors in pancreatic progenitors derived from human pluripotent stem cells (hPSCs). The technique is applicable in 2D monolayer cultures and is consistent across various pluripotent stem cell lines.
