Stem Cells and their History

What are stem cells?

Stem cells are cell develop in animal which is plastic in nature and differentiated into types of cells. All other cells with specialized function are generated under the proper microenvironment in body.
One stem cell can produce one stem cell replica and one other type of cell which can be further differentiated and develop into cell line. Stem cell have ability to self- renew, differentiation, plasticity (moldability)

History of stem cells

In 19th century Theodor Boveri and Valentin Haecker coined the term stem cell. They both are zoologist.(Pic 2)


Artur Pappenheim was first discover the theory of blood stem cells in 20th century. He was a German haematologist. (Pic 3).
Georges Mathe was perform the bone marrow transplant using stem cell therapy in 1958.he was oncologist and immunologist.(Pic 4)
Ernest McCulloch and James Till. define the main properties of stem cells. In 1960s at university of Toronto. They also discover the blood forming stem cell and hematopoietic stem cell.(Pic 5)
In 1981 Martin Evans and Matthew Kaufman isolate the embryonic stem cell and culture it in mouse blastocysts. (Pic 6)
In 2006 Shinya Yamanaka convert the fibroblast into pluripotent stem cell by modifying the expression of genes. He win a Nobel prize. (Pic 7)

This are the about the stem cells and the history. We will study about the types of stem cells.

History of Microbiology 1

Image
We will learn the history of Microbiology today... Let us start with the Pre-Golden Era. Pre-Golden Era-  Period before 1865 Experienced slow accumulation of some facts about bacteria's Theory of Abiogenesis Previously it was considered that living organisms or creatures arise from non-living matter. This belief is referred to as theory of spontaneous generation or Abiogenesis. Frogs, flies and mice were believed to have originated spontaneously from soil, fertile mud , decaying living organisms, etc. Aristotle was in support of this theory of abiogenesis. Virgil and helmont were also in the favor of the same. Discovery of Microscope Robert Bacon was the first who described lens for the first time. Hans and Janssen produced a first microscope of crude type. Gallielo Galleilee had also made a microscope with a focusing device. Fabri gave the name 'Microscope'. Discovery of Microbial Life Robert hooke had observed cells in the cork of a stem...

Mendel's Experiment and his laws 1

Image
In last Article we understood what is genetics and what are its applications , now let us study Mendelian genetics.i.e. the experiments carried out by Mendel and the laws proposed by him. Gregor Johann Mendel A priest and teacher from Brunn was sent to university of Vienna for higher studies in physics, mathematics and natural sciences. In 1856 he started his experiments on garden peas(Pisum sativum). Unfortunately his work had remained unnoticed for many years till the findings were rediscovered by three scientists independently. They are- 1.Hugo De Vries from England 2.Karl Correns from Germany 3.Erich Tschermak from Austria Based on Mendel's principle Correns postulated three laws which are known as Mendel's laws of inheritance. Before studying Mendel's experiments let us get introduced to some important terms: Character- It is a feature of an organism.Ex. Height, seed colour,etc. Trait- An inherited character and its desirable variant.E...

Mendel's Experiment and his laws 2

Image
Mendel performed three experiments- 1. Monohybrid cross 2. Dihybrid cross 3. Trihybrid cross We will study two of them first in this article. 1. Monohybrid cross  It is a cross between two pure individuals(Parents) which are homozygous in which inheritance pattern of only one pair of contrasting characters is studied. Procedure of experiment- Step 1-Selection of parents and obtaining pure lines He selected pure tall pea plant as female plant(TT) and pure dwarf pea plant as a male parent(tt). He confirmed that the plants are true breeding by selfing them for three generations. Step 2-Artificial cross of the selected plants to raise F1 generation He then performed artificial cross, collected seeds, sowed them and waited for the results. He had expected that either the offspring's would be of intermediate height or 50% of them will be tall and 50% of them will be dwarf. But amazingly all were tall and dwarfness disappeared. Step 3-Selfing of F1 hybrids to raise...
