Quantification of myofibers and undifferentiated cells of human origin in each experimental condition or independent replicate (Rep 1, 2, and 3). Schematics represent immunostaining patterns considered as myofibers of human origin (hMyofibers) or undifferentiated cells of human origin (hLamin A/C+ only). Values indicate minimum, maximum, median, and 25th and 75th percentiles.
