Use of fine needle aspiration for fibroblast culture

Diagnosis in certain metabolic diseases or the establishment of long-term reservoirs of cytogenetic material requires tissue culture of fibroblasts obtained by skin snip or punch biopsy. Fine needle aspiration biopsy (FNAB) was investigated as an alternative method of fibroblast collection with advantages of minimal morbidity and the potential of better patient acceptance. After flank FNAB, culture, and incubation, confluent fibroblast growth was achieved within 19 days. The number of cells produced was sufficient for potential cytogenetic or metabolic studies. Cultured fibroblasts obtained via FNAB proved to be a successful alternative to skin biopsy, with reduced trauma and better cosmetic results.
