Summary
Cultured Syrian hamster and human fibroblasts were hybridized by means of Sendai virus. The hybrids were selected chemically. They show preferential loss of human chromosomes and biochemical markers. Therefore they can be used for gene linkage and localization studies in man. Hybrids between Syrian hamster and fibroblasts of a human translocation carrier (46,X,t(14q+,Xq-)) enabled the assignment of the human nucleoside phosphorylase gene to chromosome 14 to be confirmed.
Zusammenfassung
Kultivierte Fibroblasten des syrischen Hamsters und des Menschen wurden mittels Sendai-Virus hybridisiert. Die Hybriden wurden durch chemische Selektion isoliert. Chromosomen und biochemische Marker der menschlichen Elternzellen segregieren bevorzugt aus den Hybriden. Man kann diese daher für Genkopplungs-und Genlokalisierungsuntersuchungen beim Menschen verwenden. Mit Hilfe von Hybriden zwischen Zellen des syrischen Hamsters und Zellen der Trägerin einer Translokation (46,X,t(14q+,Xq-)) konnte die Lokalisierung des Gens für die Nucleosid-Phosphorylase des Menschen auf Chromosom 14 bestätigt werden.
