Tgfb3^tm2(Tgfb1)Vk

A vector containing Tgfb1 cDNA followed by a pgk polyA sequence and a loxP flanked neomycin resistance cassette was inserted into the ATG start site of the targeted gene. Quantitative RT-PCR of RNA isolated from the tips of the palatal shelves demonstrates high Tgfb1 expression but no Tgfb3 expression in homozygotes. (J:128938)
