Andrzej Tarkowski
Andrzej Krzysztof Tarkowski (4 May 1933 – 23 September 2016) was a Polish embryologist and a professor at Warsaw University. He is best known for his pioneering researches on embryos and blastomeres, which have created theoretical and practical basis for achievements of biology and medicine of the twentieth century - in vitro fertilization, cloning and stem cell discovery. In 2002 Tarkowski with Anne McLaren won the Japan Prize for their discoveries concerning the early development of mammalian embryos. Career In 1950 Tarkowski was admitted to study at the Faculty of Biology and Earth Sciences (currently the Faculty of Biology) University of Warsaw. He graduated in 1955 with M.Sc. degree. His Ph.D. was received in 1959, and in 1963 he reached a D.Sc. degree at the Faculty of Biology, University of Warsaw. In 1972 he was appointed professor. He eventually received full professorship in 1978. From 1964 until his retirement in 2003 he was the head of the Department of Embryology ...

Chimera (genetics)
A genetic chimerism or chimera ( ) is a single organism composed of cells with more than one distinct genotype. In animals, this means an individual derived from two or more zygotes, which can include possessing blood cells of different blood types, subtle variations in form ( phenotype) and, if the zygotes were of differing sexes, then even the possession of both female and male sex organs. Animal chimeras are produced by the merger of two (or more) embryos. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division. Normally, genetic chimerism is not visible on casual inspection; however, it has been detected in the course of proving parentage. Another way that chimerism can occur in animals is by organ transplantation, giving one individual tissues that developed from a different genome. For example, transplantation of bone marrow often determines the recipient's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem Cell
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. ''In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. How ...

Order Of Polonia Restituta
The Order of Polonia Restituta ( pl, Order Odrodzenia Polski, en, Order of Restored Poland) is a Polish state order established 4 February 1921. It is conferred on both military and civilians as well as on foreigners for outstanding achievements in the fields of education, science, sport, culture, art, economics, national defense, social work, civil service, or for furthering good relations between countries. The Order of Polonia Restituta is sometimes regarded as Poland's successor to the ''Order of the Knights of Saint Stanislaus, Bishop and Martyr'', known as the Order of Saint Stanislaus, established in 1765 by Stanisław August Poniatowski, the last King of the Polish–Lithuanian Commonwealth, to honor supporters of the Polish crown. History When Poland regained its independence from the German Empire, Austro-Hungarian Empire, and Russian Empire in 1918, the new Polish government abolished the activities of the Order of Saint Stanislaus (Imperial House of Romanov) ...

Genetically Modified Animal
Genetically modified animals are animals that have been genetically modified for a variety of purposes including producing drugs, enhancing yields, increasing resistance to disease, etc. The vast majority of genetically modified animals are at the research stage while the number close to entering the market remains small. Production The process of genetically engineering mammals is a slow, tedious, and expensive process.Murray, Joo (20)Genetically modified animals Canada: Brainwaving As with other genetically modified organisms (GMOs), first genetic engineers must isolate the gene they wish to insert into the host organism. This can be taken from a cell containing the gene or artificially synthesised. If the chosen gene or the donor organism's genome has been well studied it may already be accessible from a genetic library. The gene is then combined with other genetic elements, including a promoter and terminator region and usually a selectable marker. A number of technique ...
