Written Report Stem Cell Technology Stem Cells – cells that have the ability to continuously divide and differentiate into various other kind of cells. Characteristics: * Simple‚ remain the same cell in constant environment * Continuous mitotic divisions * With proper stimuli/environment it can differentiate into various cells Classification: Type of cells | Description | Source | Totipotent | Can give rise to a whole organism | Fertilized egg cell | Pluripotent | Can

MEIOSIS We study Gametes through a Karyotype Each pair is called a homologous pair Diploid= 23 pairs of chromosomes and 46 total chromosomes (2n) Haploid= 23 individual pairs Mitosis- makes body cells‚ or asexual reproduction like cloning Meiosis- makes sex cells Crossing Over- Occurs in Prohpase I - each group of 4 chromatids are called a tetrad. Individual chromatids may wrap around eachother and pieces may break off and reattach to other chromatids. Genes on chromosomes may change places

defines stem cell research‚ the pros and cons of stem cell research‚ and the debate regarding the methods of this intense subject. There are researchers‚ scientists‚ and doctors discovering ways to benefit the terminally ill and‚ in many cases‚ even cures for those people with the use of stem cells. Even though this may sound as though it would produce only a positive outcome‚ it is also a debatable subject. The majority of the vote against this research is due to moral issues. A stem cell is not

cloning is embryonic stem cells for experiments to replace injuries or diseased cells. Cloning can be used for many reasons such as medical research‚ endangered or extinct species could be recreated‚ reproducing a loved pet that is deceased‚ cloning livestock for a higher quality milk or meat‚ and also

This pales in comparison to China‚ Europe and the U.S.‚ which each report 100‚000 clients on average. The global market for stem cell therapies is expected to be $20 billion (Rs 92‚593 crore) by 2010. The current stem cell therapy market in India is approximately $540 million and it is expected to grow rapidly. This shows the scope in the market for stem cell banking. India is one of

by two scientists. They are Sir John B. Gurdon from United Kingdom and Prof. Shina Yamanaka from Japan. They both contribute to develop human cell studying. Official Nobel Prize announced that the Prize motivation is "for the discovery that mature cells can be reprogrammed to become pluripotent". They discover that mature cells can be converted to stem cells. Sir John B. Gurdon was born in Dippenhall in 1933. He is a British developmental biologist‚ which is the discipline of organism grow and

If the cornea is scratched‚ healthy cells quickly heal the scratch before it gets an infection. If the damage is serious‚ the person can receive a cornea transplant. Also‚ scientists have discovered a new way to repair the cornea by using stem cells. 3. A cornea transplant is when a section of a damaged cornea is removed and replaced with a healthy cornea from a donor. Only about 20% of the
