BMP7 expression in mammalian cortical radial glial cells increases the length of the neurogenic period. BMP7 expression in mammalian cortical radial glial cells increases the length of the neurogenic period

Purpose:To asses changes in gene expression profiles of single cell from the E39 Ferret Cortex. Mouse E18 littermate controls cortex, and Smo CKO (SmoF/F hGFAP-Cre) mice. Methords: E39 ferret cortex, E18 wild type and Smo CKO cortices were carefully dissected under a fluorescent stereoscope, and incubated in 4 ml of papain solution for 20 min at 37℃, The cortical tissues were gently triturated, filtered through a 40 mm strainer, and washed with HBSS to obtain the single cell suspension. The Chromium droplet-based sequencing platform (10X Genomics) was used to generate scRNA-seq libraries, following the manufacturer’s instructions. The cDNA libraries were purified, quantified using Agilent 2100 Bioanalyzer, and sequenced on the Illumina Hiseq4000 Results: E18 SmoF/F (control) cortex, 10524 cells, 1954 genes/cell; hGFAP-Cre; SmoF/F cortex, 7596 cells, 2104 genes/cell; E39 ferret cortex, 23482 cells, 1759 genes/cell. Overall design: scRNA-seq: Individual cells were sampled from mice cortices of E18 wild type mice and Smo CKO mice,and E39 ferret cortex.
