Cell-autonomous action of nrd. Cell transplantation experiments providing donor clones in the dorsal spinal cord

Transplantation donor into recipient	Number of recipient embryos with donor derived RBs	Total number of recipients with donor derived cells in the dorsal spinal cord*
Mutant into wildtype	0	6
Wildtype into mutant	3	3
Mutant into mutant	0	1

^*Note: the total number of surviving transplants analyzed to obtain these numbers was 286. It is a rare event to find cells within the dorsal spinal cord.
