Procreate<\/strong> from semen and a skin cell is science and non-fiction<\/strong><\/span><\/p>\n

Cient\u00edficos brit\u00e1nicos han obtenido 30 cr\u00edas de rat\u00f3n fecundando los tejidos fetales y no el \u00f3vulo. No descartan que la tecnolog\u00eda sea aplicable al ser humano.<\/strong><\/span><\/p>\n

Un grupo de microbi\u00f3logos ha logrado\u00a0estabilizar el desarrollo de fetos de rat\u00f3n engendrados sin fertilizaci\u00f3n. Normalmente, cuando se logra activar los \u00f3vulos sin espermatozoide los embriones mueren y se desintegran por falta de la informaci\u00f3n gen\u00e9tica necesaria. El experimento busc\u00f3 poder proporcionarles esa informaci\u00f3n utilizando esperma, pero en fases de partenog\u00e9nesis<\/a>\u00a0ya muy avanzadas.<\/span><\/p>\n

El \u00e9xito de una serie de pruebas con ratones de laboratorio, descrita en un art\u00edculo de la revista ‘Nature Communications’<\/a>, abre el camino a la fecundaci\u00f3n de distintos tipos de tejidos, aseguran los autores. Potencialmente no solo los \u00f3vulos sirven para engendrar, pues la esperma puede ser fundida con c\u00e9lulas ordinarias provenientes de la piel u otro tejido. Estas c\u00e9lulas podr\u00edan ser activadas para obtener descendencia, opina el experto en embriolog\u00eda Tony Perry, de la Universidad de Bath (Reino Unido).<\/span><\/p>\n

El cient\u00edfico se\u00f1al\u00f3 al peri\u00f3dico brit\u00e1nico ‘Metro’<\/a>\u00a0que proyectar las primeras conclusiones \u00a0en ratones a la posible reproducci\u00f3n humana es \u00abcompletamente especulativo e imaginario\u00bb, pero no lo descarta totalmente. En un futuro, por ejemplo, los hombres homosexuales podr\u00edan tener hijos\u00a0mediante la fecundaci\u00f3n en probeta de la c\u00e9lula de la piel de uno y el esperma de otro, y un hombre incluso podr\u00eda\u00a0tener descendencia que contara con una mezcla de genes suyos y de sus padres.<\/span><\/p>\n

Los ratones de Perry dejaron un total de 30 cr\u00edas, pero los progenitores eran siempre una hembra y un macho, aunque este particip\u00f3 de manera indirecta y tard\u00eda. La eficacia de estos experimentos se estima en un 24%, un \u00edndice de \u00e9xito, seg\u00fan el autor, muy superior\u00a0al 1%-2% de los experimentos\u00a0de\u00a0clonaci\u00f3n<\/a>\u00a0realizados a partir de c\u00e9lulas adultas, como el de la oveja Dolly.<\/span><\/p>\n

Algunos de los ratones obtenidos tuvieron descendencia de manera natural, lo que los bi\u00f3logos interpretan como una se\u00f1al de buena salud y condici\u00f3n f\u00edsica normal. Para el equipo cient\u00edfico, el paso siguiente ser\u00eda tratar de fecundar con semen a una hembra de rat\u00f3n mediante una c\u00e9lula no\u00a0sexual ni\u00a0obtenida mediante partenog\u00e9nesis<\/span><\/p>\n

British scientists have obtained 30 mouse pups fertilizing fetal tissues and not the egg. Not rule out that the technology is applicable to the human being.<\/span><\/p>\n

A group of microbiologists has managed to stabilize the development of mouse fetuses born without fertilization. Normally, when is manages to activate them eggs without sperm the embryos die and is disintegrate by lack of it information genetic required. The experiment sought to provide that information using sperm, but in phases of already very advanced parthenogenesis.<\/span><\/p>\n

The success of a series of tests with laboratory mice, described in an article in the journal ‘Nature Communications’, opens the way to fertilization of different types of tissues, say the authors. Potentially not only the eggs are used to spawn, because sperm can be fused with ordinary cells from skin or other tissue. These cells could be activated for descent, writes in embryology expert Tony Perry, of the University of Bath (United Kingdom).<\/span><\/p>\n

The scientist told the British newspaper ‘Metro’ that projecting the first findings in mice to possible human reproduction is \u00abcompletely speculative and imaginary\u00bb, but do not discard it completely. In the future, for example, gay men may have children through fertilization in test tube of one skin and sperm of another cell, and a man could even have offspring that counted with a mixture of his genes and their parents.<\/span><\/p>\n

Perry mice left a total of 30 broods, but parents were always a female and a male, although it participated in late and indirect way. The effectiveness of these experiments is estimated at 24%, a success rate, according to the author, far superior to 1% – 2% of experiments of cloning from adult cells, such as the sheep Dolly.<\/span><\/p>\n

Some of the mice obtained had offspring naturally, what biologists interpret as a sign of good health and normal physical condition. For scientific equipment, the next step would be to try fertilizing with sperm to a female mouse using a cell not sexual or obtained by parthenogenesis<\/span><\/p>\n
