Generation of ASCL1-mCherry knock-in reporter in human embryonic stem cell line, WAe001-A-2E, using CRISPR/Cas9-based gene targeting
Summary
Achaete-Scute Complex Homolog 1 (ASCL1) is a key regulator in the development and function of the nervous system, particularly in the process of neuronal and neuroendocrine cell differentiation. By employing the CRISPR/Cas9 system, we successfully established an ASCL1-mCherry knock-in human embryonic stem cell (hESC) line by inserting a P2A-mCherry fragment at the ASCL1 locus. The mCherry reporter effectively demonstrated the expression level of endogenous ASCL1 during the process of inducing pulmonary neuroendocrine cells (PNECs) from hESC. This reporter cell line holds significant value as a research tool for investigating the process of lung neuroendocrine cell differentiation, conducting drug screening, and exploring the underlying mechanisms of lung diseases associated with PNECs dysfunction.
