Control of Differentiation by Intraorganismic Environment (With Experiments) | Embryology

In this article we will discuss about:- 1. The Problem of Reversibility of Differentiation 2. Chemical Substances as Means of Controlling Differentiation 3. Epithelial-Mesenchymal Interactions. The Problem of Reversibility of Differentiation: Differentiation may be reversible to a certain extent. The morphological and physiological peculiarities of tissues require for their maintenance the environment which surrounds them in the normal organism. Except [...]

Differentiation Out of Control (With Experiment) | Embryology

In experiments of disaggregation and re-aggregation of embryonic cells, there sometimes arise complexes in which differently differentiated tissues are present in chaotic arrangement, having no relation, or only a slight relation, to the arrangement of the same tissues in a normal individual. We have referred to such complexes as teratomas (Fig. 454). The term "teratoma," however, was originally coined to [...]
