NF1 and sarcoma: To do so, we performed immunostaining using NF1 and p53 antibodies on normal sciatic nerves (no injury) from wild-type mice (n = 8), injury-induced sciatic nerves from NPcis mice that develop pNF (n = 12), injury-induced sciatic nerves from NPcis mice that did not develop (n = 9) pNF and spontaneous sarcoma from NPcis mice (n = 23) “Fig 7a”.
