Beschreibung:
A strategy was devised for identifying regions of the mouse genome that are transcriptionally active in a temporally and spatially restricted manner during development. The approach is based on the introduction into embryonic stem cells of two types of lacZ reporter constructs that can be activated by flanking mouse genomic sequences. Embryonic stem cells containing the lacZ constructs were used to produce chimaeric mice. Developmental regulation of lacZ expression occurred at a high frequency. Molecular cloning of the flanking endogenous genes and introduction of these potential insertional mutations into the mouse germ line should provide an efficient means of identifying and mutating novel genes important for the control of mammalian development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gossler, A -- Joyner, A L -- Rossant, J -- Skarnes, W C -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):463-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Division of Molecular and Developmental Biology, Toronto, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497519" target="_blank"〉PubMed〈/a〉
