Tissue Combination and Organ Culture Studies in the Development of the Embryonic Mammary Gland,ow of the great importance of tissue interaction in the development of these organs. Two special features distinguish the mammary gland from otherwise comparable organs. First, while the development of most epithelial-mesenchymal organs is more or less completed during the embryonic or fetal period,

The Immunological Approach to the Study of Preimplantation Mammalian Development,ms and cellular interactions involved in the transition of a single cell, the zygote, into a complex multicellular organism. The mouse has proved the most useful model for such studies because development of the preimplantation embryo . appears to parallel development .. During this period the embry

Nuclear and Cytoplasmic Transfer in Mammalian Embryos,cleus should permit a functional assessment of nuclear potential. Similarly, the transfer of foreign cytoplasm will expose the host nucleus to cytoplasmic signals not normally encountered and thus serve to define cytoplasmic controls in development. Since experimental manipulations of this type requ

Oocyte Fusion, chemical fusing agents or viruses occurs as a natural phenomenon during the formation of polykaryote cells. Spontaneous cell-to-cell fusion represents a very specific event; that is, under normal conditions the extent of fusion is regulated by the participant cells. Common to all spontaneous cell f

Manipulation of Early Mammalian Development: What Does It Tell Us about Cell Lineages?, types of early embryo are analyzed more carefully, however, it becomes clear that the general principles underlying their development are not too dissimilar from those that apply to the mouse (see Johnson and Pratt, 1983, for discussion). The capacity to regulate, the importance of cell interaction
