Direct comparison of the course would be difficult between tissues and cultured cells. In stead of time scale, you might want to use markers. For example, Kislinger et al. show the expression peak of SIX1 is 2 days after differentiation; SMAD3, 4 days. I am not a right person who can tell which markers are good, but I believe you could find more information ...


Some background: The new work involved misexpression of the Drosophila Ubx protein in the presumptive thorax of transgenic fruitfly embryos. Limb development was suppressed because of repression of Dll. By contrast, the misexpression of onychophoran and crustacean Ubx proteins did not interfere with Dll expression and the formation of thoracic limbs. ...
