Stem cells

leftover blood that is in the placenta and the section of the umbilical cord that remains attached to the placenta after the cord to the baby has been cut. This blood contains red blood cells, white blood cells, platelets and plasma, just like normal blood. But it also has lots of hematopoietic (blood-forming) stem cells that are similar to the ones found in bone marrow. This is why cord blood is now being used on an experimental basis as an alternative to bone marrow transplants for patients…

The use and research on embryonic stem cells is an extremely controversial issue. Today i will explore both sides of the argument and then come to a conclusion. Embryonic stem cells come from a blastocyst. A blastocyst is formed when the egg has divided into about 100 cells during development. This usually happens at around 5 days after fertilisation. The embryos used are leftover from IVF treatment. IVF stands for in vitro fertilisation and it is used when a couple is not able to conceive…

an emotionally charged historical account regarding the origin of one of the most famous and important tools in modern medicine. The HeLa Cells, taken from Mrs. Henrietta Lacks in the early 1950’s without her consent, have lead to researchers finding a multitude of new treatments and making a myriad of new discoveries and even mass farming and distribution cells since then. But not without great human consequence and strife. Could it be something such as religion that holds what’s left of…

From stem cell research to cryonics to artificial organs, mankind has gained immense knowledge.Considering today's circumstances with research done, the possibility of Frankenstein's monster being successful is much more…

1) What is the question the authors are trying to answer? - The authors are trying to determine if progesterone would make a difference on the quality of the embryos during the growing stage of the first follicular wave. 2) What is the hypothesis of the study? - The hypothesis of this study is that if a person were to induce a cow to ovulate follicles during the first follicular wave, that would minimize the embryo quality due to progesterone concentration at the time of growing the follicle…

Over the past few decades a lot of biomedical information has been gathered (in the form of images, signals and sequences) and there is a great deal of knowledge that can be gathered from the raw data \cite{manyika2011big}. The biomedical imaging data consists of magnetic resonance image (MRI) \cite{edelman1993magnetic, ogawa1990brain}, radiographic image \cite{hsieh2009computed, chapman1997diffraction}, positron emission tomography \cite{bailey2005positron} and others. Biomedical signaling data…

The reproductive cloning of human embryos is largely considered unethical because a human clone would have a greatly decreased quality of life; clones often suffer from genetic and physical abnormalities, and have greatly shortened lifespans. Others fear that the reproductive cloning of human embryos has the potential to be abused. In theory, one could create human clones for purpose of organ harvesting. For these reasons, many countries have halted research on the reproductive cloning of humans…

from other parts of the body are not suitable for the coronary artery bypass, then a replacement blood vessel must be used. My goal is to make a blood vessel replacement that is durable, strong, flexible, comfortable, interacts well with surrounding cells and tissues, all while being as inexpensive as possible. I believe the best way to achieve this goal is to create my own novel design. I can study existing technologies to see where prior technologies failed or suffered and use my ideas to fix…

do the stem cell justice. Stem cells are cells that have yet to develop a purpose. They are used in various tissues and organs throughout the body to repair and replace cells that can no longer preform their function properly. The term stem cell was first used in 1868 by biologist Ernst Haeckel. He was using the term to describe a fertilized egg that becomes an organism. This is the basis of what an actual stem cell is, one type of cell that becomes another. The next advance of the stem cell…

“Will Technology Ruin Your Children’s Development?” published by Dhruvin Patel is a good article for research because the author displays extensive experience in the medical field and uses advanced research. Also, the publication explores the topic through more than one perspective; it is known of the favored side while the opposing side isn’t criticized. Patel’s article is also up-to-date with it being published this year. Furthermore, “Creating Balance in the New Age of Technology” by Jana…
