Two ‘ethical’ ways to harvest stem cells an “embryo” capable of becoming the twin of the patient if implanted into the womb has to be destroyed in order to obtain the escs needed to. Embryonic stem cells that have proliferated in cell culture for six or more months without differentiating, are pluripotent, and appear genetically normal are referred to as an embryonic stem cell line at any stage in the process, batches of cells can be frozen and shipped to other laboratories for further culture and experimentation.
Pros and cons of stem cell research share flip pin email that also provides alternatives for obtaining viable stem cell lines out of necessity, the research on these alternatives is catching up with embryonic stem cell research and, with sufficient funding, other solutions might be found that are acceptable to everyone. Stem cell research methods of obtaining embryonic stem cells with, perhaps, fewer ethical objections sponsored link the ethical dilemma: there is a general consensus that all living matter containing human dna is, by definition, human life this may include human life in the form of a spermatozoon, ovum, pre-embryo, embryo, fetus, newborn, child, youth or adult. Human embryonic stem cells (escs) are pluripotent cells, meaning cells that can make any other cell in the body they are made from cells found in very early human embryos, called blastocysts many areas of science use mouse escs to study how blastocysts grow into adults and to study what signals direct stem cells to differentiate into specialised cells. Obtaining mesenchymal cells, or stem cells, from umbilical cord is an extremely sensitive and complicated procedure it takes highly skilled and experienced people and state-of-the-art technology working in tandem with each other.
Once an egg cell is fertilized by a sperm, it will divide and become an embryo in the embryo, there are stem cells that are capable of becoming all of the various cell types of the human body for research, scientists get embryos in two ways many couples conceive by the process of in vitro. The main reason for this type of research is that doctors need to obtain stem cells in order to correct damaged lungs, but the current process of actually obtaining these cells is extremely difficult and risky. A recent study at uc san francisco has reported new findings in how cell reconstruction can change the standard methods in the way we obtain and treat stem cells the newly-discovered process takes adult cells and reverts them back to an embryonic state by identifying the bio-chemical pathways.
These induced pluripotent stem (ips) are conventional in replacing the conventional need for obtaining stem cells from embryotic tissue however, the hype is currently undermined as the success rate for transforming adult cells into ips blank cells is rather low. They hope to find a method of obtaining stem cells that is acceptable to the pro-life movement the stakes are very high embryonic stem cells have the potential to develop into almost any of the 220 types of cells found in the human body (eg blood cells, heart cells, brain cells, nerve cells, etc. If fetal stem cells are obtained from miscarried or stillborn fetuses, or if it is possible to remove them from fetuses still alive in the womb without harming the fetuses, then no harm is done to the donor and such fetal stem cell research is ethical. Embryonic stem cells are grown from cells found in the embryo when it is just a few days old in humans, mice and other mammals, the embryo is a ball of approximately 100 cells at this stage.
Embryonic stem cells can make copies of themselves and make other types of more specialized cells mouse es cells can be put back into a mouse blastocyst and this blastocyst can then be returned to the uterus of a female mouse to develop into a foetus.
In order for stem cells to be cultivated, the pluripotent cells have to be alive it must have the potential to be multiplied the source of the cell must also be alive.
