MFGE8-positive astrocytes partially originate from FOXG1-cre expressing progenitors. (A) Lineage tracing of FOXG1-expressing cells with a YFP reporter mouse line demonstrates that MFGE8 astrocytes can derive from FOXG1-expressing and other progenitors in (A) cerebral cortex (CTX) and hippocampus (HIP) and in (B) the caudate putamen (cPA). Magnifications show single MFGE8- and YFP-positive (MFGE8+/YFP+) cells in (a”) cerebral cortex, (a”’) hippocampus and (b”,b”’) caudate putamen. MFGE8+/YFP-negative cells are illustrated in (a’) the cerebral cortex and in (b’) the caudate putamen. Scale bar: 10 μm, n = 3. (C) Overview images of representative rostral and caudal forebrain section after immunofluorescence for MFGE8 and GFP show the region analyzed in (A,B) as indicated.
