Lineage Analysis of HuCNS-SC CCL in the 9 DPI Paradigm
Data for proportional human cell fate were collected by blinded, unbiased stereology
(A) Immunostaining for STEM121 (brown) and DCX (blue) revealed no STEM121+/DCX+ cells in CCL 9 DPI animals. Inset shows positive control for DCX in cortex.
(B) Immunostaining for human-specific GFAP (STEM123, brown) with hematoxylin counterstaining (purple) revealed 33% ± 4.4% of CCL 9 DPI were positive for this astroglial marker.
(C) Immunostaining for STEM121 (blue) and Olig2 (brown) revealed that the largest proportion of STEM121+ cells in the 9 DPI transplant group were positive for this oligodendroglial marker (57.6% ± 2.4%).
(D) Immunostaining for STEM121 (brown) and CC1 (blue) revealed 13.6% ± 3% of CCL 9 DPI were positive for this mature oligodendroglial marker.
Arrowheads indicate double-positive cells. n = 7 for all lineage tests. Data shown as means ± SEM.
