The thymus is the primary organ responsible for generating functional T cells in vertebrates. Although T cell differentiation within the thymus has been an area of intense investigation, the study of thymus organogenesis has made slower progress. The past decade, however, has seen a renewed interest in thymus organogenesis, with the aim of understanding how the thymus develops to form a microen...

(Ultrastructural analysis of in vitro direct and indirect organogenesis). This is a comparative study of the ultrastructural characteristics of the cells involved in the organogenesis in vitro of Bauhinia forficata Link (indirect system) and Glycine max (L.) Merrill (direct system). B. forficata calli after 30 days culture and G. max meristemoids after 10 days culture were prepared for ultrastr...

The discovery of tissue stem cells has launched the current boom in the field of regenerative research, which is tremendously exciting and holds enormous therapeutic potential. Despite such optimism, recent findings have tempered the potential for medical practice. Anatomically complicated organs, such as the kidney, have proved refractory to stem cell-based regenerative techniques. As the kidn...
