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. scRNA-seq: Individual cells were sampled from mice cortices of E18 wild type mice and Smo CKO mice,and E39 ferret cortex.
