Bioethical aspects of basic research and medical applications of human stem cells
Provedor de dados: 48
Autores: Santos,Manuel J; Ventura-Juncá,Patricio.
The new discoveries, the extraordinary dynamism in human stem cell (SC) research, and the great expectations of the benefits in clinical treatment of many diseases are on the edge of unparalleled advances in both: 1) the understanding of basic mechanisms of cell differentiation and development and 2) the translation from basic research to new clinical therapies. Human stem cells are obtained from different sources, such as embryo, fetal, and adult tissues, in vitro induction (iPS cells) or transdifferentiation. The evidence that these cells are pluripotent (or multipotent), meaning they have the ability to differentiate into all body tissues or tissues of the same lineage, raises the possibility that they could regenerate diseased or damaged tissue in...

The beginning of life of a new human being from the scientific biological perspective and its bioethical implications
Provedor de dados: 48
Autores: Ventura-Juncá,Patricio; Santos,Manuel J.
The issue of when the human life begins is a very important subject since it has a significant impact on the decisions that we have to take in relation to human beings in development, particularly human embryos. In this article we discuss some of the more relevant biological evidence supporting the fact that beginning human life begins unquestionably at fertilization and the bioethical consequences.

In vitro fertilization (IVF) in mammals: epigenetic and developmental alterations. Scientific and bioethical implications for IVF in humans
Provedor de dados: 48

The advent of in vitro fertilization (IVF) in animals and humans implies an extraordinary change in the environment where the beginning of a new organism takes place. In mammals fertilization occurs in the maternal oviduct, where there are unique conditions for guaranteeing the encounter of the gametes and the first stages of development of the embryo and thus its future. During this period a major epigenetic reprogramming takes place that is crucial for the normal fate of the embryo. This epigenetic reprogramming is very vulnerable to changes in environmental conditions such as the ones implied in IVF, including in vitro culture, nutrition, light, temperature, oxygen tension, embryo-maternal signaling, and the general absence of protection against foreign...
