Figure 2From: Commitment of chondrogenic precursors of the avian scapula takes place after epithelial-mesenchymal transition of the dermomyotomeAssessment of the grafting experiments. After a re-incubation period of 5 hours the operated embryos were harvested, sectioned and stained with quail-specific QCPN antibody. A) Nuclear (blue dot) QCPN signal (black arrow) is confined to a small population of grafted dermomyotomal cells. B) Grafted SEM of quail origin (stained in brown) is located in the sub-ectodermal region (black arrow). dm, dermomyotome; m, myotome; n, neural tube; scl, sclerotome; sem, sub-ectodermal mesenchyme (Scale bar = 150 μm).Back to article page
