Comparative measurements of collagen synthesis as a portion of total protein synthesis were performed with fragments of peripheral neurofibromas, of skin adjacent to the tumors, and of unaffected skin from patients with neurofibromatosis (NF). No significant difference was found among these various

β¦ Synopsis
The X-ray sensitivity of strains of fibroblast-like cells derived from peripheral neurofibromas of ten patients with neurofibromatosis was compared with that of 12 strains of skin fibroblasts derived from healthy donors. Quantitative parameters of the dose-dependent reduction in colony-forming ability did not differ significantly between these two groups of strains. The cloning efficiencies of nonirradiated controls varied within the same range in strains derived from patients and from healthy donors.

Cell cultures grown from peripheral neurofibromas of three patients suffering from sporadic peripheral neurofibromatosis (NF) were analysed cytogenetically at early in vitro passages. The NF-cultures exhibited a 6.7-fold higher frequency of aneuploid mitoses, including pseudodiploids, than the contr
Three cases with co-existent Wilm's tumor and Von Recklinghausen's Disease from a series of 342 nephroblastomas are discussed as to the significance of this association. Biological arguments favor a positive link because of the multiplicity of associative lesions which parallel each other, the co-ex
