1. Oocytes, embryos and pluripotent stem cells from a biomedical perspective
Abstract The veterinary and animal science professions are rapidly developing and their inherent and historical connection to agriculture is challenged by more biomedical and medical directions of research. While some consider this development as a risk of losing identity, it may also be seen as an opportunity for developing further and more sophisticated co

2. Cloning and expression analysis of the transcription factor Scratch2 during the chicken early embryogenesis. / Clonagem e análise da expressão do fator de transcrição Scratch2 durante a embriogênese inicial de galinha.
In invertebrates, the Scratch (Scrt) genes encode transcription factors that promote neurogenesis during development. The Scrt function in vertebrates is unknown, but in mice Scrt1 and Scrt2 are specifically expressed in post-mitotic neurons in the embryo and in the adult central nervous system. In this work, we have cloned the coding sequence of chicken Scr

3. Análise ético-constitucional da utilização de embriões humanos em experimentos científicos.
This work aims to carry out an analysis ethics and legal about the constitutionality of the use of human embryos produced in vitro in scientific experiments. The doctrine about the subject is scarce and it appears quite divided. For someone there would not be any ethical or legal problem in the use of human embryos in such experiments although these would no

4. Effect of conditioned medium of mesenchymal stem cells on the in vitro maturation and subsequent development of mouse oocyte
Mesenchymal stem cells (MSCs) secrete a variety of cytokines and growth factors in addition to self-renewal and multiple forms of differentiation. Some of these secreted bioactive factors could improve meiotic maturation in vitro and subsequent embryo developmental potential. The aim of the present study was to determine whether in vitro maturation (IVM) of

5. Limitações jurídicas às pesquisas em células-tronco embrionárias.
The objective of this dissertation is to examine some of the legal implications of the biotechnological revolution as well as its reflexes on the body of legal knowledge as a hole specially in what concerns embryonic stem cells for therapeutic use abiding by Brazilian Federal Statue 11.105/2005. The paper alerts to the relevance of preserving such research w

6. O bem jurídico-penal tutelado pelo crime de utilização ilegal de células-tronco embrionárias humanas (artigo 24 da Lei de Biossegurança)
Esta dissertação busca esclarecer qual é o interesse protegido pelo legislador quando incrimina a utilização ilegal de células-tronco embrionárias humanas no artigo 24 da Lei n 11.105/2005 também conhecida como Lei de Biossegurança. Isto se deve ao fato de que ao tempo em que incrimina a ação, o legislador o faz apenas sob certas condições: aque
