Fig. 2. Spatial and temporal expression of Bcre-32 using the ROSA reporter
demonstrates Cre-mediated recombination in the neural tube. (A) lacZ
expression at 8.5 dpc in the anlage of the diencephalon and mesencephalon. (B)
By 9.75 dpc, Bcre32-mediated recombination has targeted the rostral
neural tube, including the developing brain and the rostral spinal cord, but
largely excluding the telencephalon. (C) lacZ expression throughout
the neural tube by 10.5 dpc indicating widespread Bcre32-mediated
recombination, except in the dorsomedial telencephalon and regions of the
ventral forebrain (detail not shown). (D) At 9.75 dpc, lacZ
expression demonstrates Bcre32-mediated recombination throughout the
neural ectoderm.
