The expression of apln and apela at different stages.
(A. a1-a8) The expression of apln from 75% E to 20 SS. At 75% E, apln was not expressed in the embryos (A. a1-a2). At bud to 5 SS, apln was expressed in the midline (A. a3-a6, arrow showed). At 20SS, apln was expressed in midline (A. a7, right arrow; a8, up arrow) and heart progenitor field (A. a7, left arrow; a8, down arrow). (B. b1-b8) The expression of apela from 75% E to 15 SS. At 75% E, apela was expressed ubiquitously (B. b1). At bud stage, apela was expressed in the midline and presomite mesoderm (PSM) (B. b2-b3). At 5SS, apela was expressed in the midline and KV epithelium (B. b4-b5, arrow head). At 15SS, apela was expressed in midline and heart progenitor field (B. b6-b8, arrow).
