Strain developmentDeveloped by Dr. Hidemi Misawa at Tokyo Metropolitan Institute for Neuroscience in 2003. The VaChT-Cre transgene was injected into the pronuclei of fertilized oocytes of C57BL/6 mice.
Strain descriptionTg(SLC18A3-cre)KMisa, RBRC01515, is a transgenic Cre-driver mouse line, in which Cre expression is driven by the 11.3 kb human vesicular acetylcholine transporter (VAChT) promoter (Misawa et al., 2003). The lines showed restricted Cre expression in approximately one half (40-60%) of the postnatal somatic motor neurons and cholinergic neurons of the medial habenular nucleus. Transgenic expression was not observed in visceromotor or other central or peripheral cholinergic neurons. Cre expression began on approximately postnatal day 7 and reached at maximal levels by 5 weeks of age (earlier onset than Tg(SLC18A3-cre)AMisa, RBRC01516). Re-evaluation (Misawa et al., 2016) of the line by using subtype selective markers showed preferred Cre expression in slow-type motor neurons (S- and FR-type) innervating type I or IIa muscle fibers. To avoid confusion the common name of the line was changed from VAChT-Cre.Fast to VAChT-Cre.Early. Ref. Genesis, 54, 568-572 (2016).
