+ denotes greater than 200 cells

n/d denotes specimens not stained for STELLA

1

Chimera exhibited a host-derived double omphalomesenteric artery.

2

Circulating within dorsal aortae, omphalomesenteric artery, and/or vessel of confluence.

3

Includes general loose mesenchyme and/or mesoderm associated with somatopleure.
