Focuses on the federal assistance on research of embryonic stem cell lines in the U.S. Debate on the usefulness, quality, characteristics and availability of cell lines; Issue on the expectation for effectiveness of stem cells in treatment of diseases; Historical background on the stem cell ...
What is Embryonic Stem Cell Research? What are Somatic Cells? Discussion Comments By EdRick — On May 25, 2011 @robbie21 - Yes, a blastocyst has not yet implanted. Apparently, a blastocyst isn't an embryo yet. (In humans, the term embryo only applies after implantation.) At the blast...
Jun 05, 2024 - Mesenchymal stem cells (MSCs) are adult stem cells with the ability to differentiate into various types of mesoderm-derived cells, showing promising results in preclinical studies for various medical conditions. Research continues to explo
I ve done 89 trips — of those, 51 have been abroad. I have 42 hours to carry stem cells(干细胞) in my little box because I ve got two ice packs and that s how long they last. In all, from the time the stem cells are harvested from a donor(捐献者) to the time they can b...
Embryonic Stem Cells These cells are taken from embryos in the first stages of their development. They can become different types of cells and are often promoted as having great potential for regeneration in some diseases. We never use them at Swiss Medica for two main reasons: ...
Stem cells are present in a variety of tissues, such as bone marrow, embryonic tissue, and even some adult tissues. Answer and Explanation: The source of hematopoietic stem cells (HSCs) is the (a) red bone marrow. All blood cell types,...
Human embryonic stem (hES) cells have the potential to differentiate into any desired cells and to be used in cell replacement therapies for some diseases. However, existing hES cell lines would not be suitable for the therapies as they are contaminated with other biological products. In order ...
There are several sources of stem cells: Embryonic stem cells.These stem cells come from embryos that are 3 to 5 days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more...

视神经乳头正常的时候有一个生理凹陷，如果超过了正常大小就可能形成一个杯，正常人的杯和盘不会差别很大的，不超过0.5，就是杯和盘的比例。杯盘比增大，很多情况下是病理性的，比方说青光眼，青光眼引起视神经萎缩，他可能表现在杯盘比的增大。但是咱们换一个角度来讲，是不是杯盘比大的人就一定...
