Single-cell RNA-seq analysis of p53 knockout primary astrocytes in vitro.
To investigate the mechansims that underly astrocyte dedifferentiation, we performed single cell RNA sequencing analysis of primary astrocytes after p53 loss and exposure to mitogens, EGF and and FGF. Primary astrocytes were isolated from postnatal day 3 inducible p53 knockout mice (GFAP-CreERT2;p53flox/flox;LSL-tdTomato), whereby treatment with 4-hydroxytamoxifen (4OHT) induces p53 loss and tdTomato labelling in GFAP+ astrocytes. Astrocytes were treated with 4OHT in media supplemented with EGF and FGF to induce recombination and astrocyte dedifferentiation in vitro. Overall design: Primary astrocytes from a total of 4 mouse brains (2 mice pooled per independent replicate) with raw data for 12,040 single cells.
