The Function Of The Hair Follicle Stem Cells - 1239 Words

An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins. Hair follicle stem cells are responsible for not only its self-renewal but also in the production of rapidly multiplying cells. The stem cells of the hair follicle are for temporary increase in cells, and are created by the differentiation of hair follicle stem cells. The focus of this essay will be to analyze a specific protein within the hair follicle stem cell BMP, bone morphogenetic proteins. Through intrinsic expression, Bone morphogenetic proteins (BMPs) are able to function in multi levels and are in charge for the transforming growth factor beta (TGFbeta). These proteins are crucial for the maintenance and the proliferation of hair follicle stem cells. Bone morphogentic proteins have the ability to affect other molecules that are part of the niche, which boosts or limits particular cell ular functions to the needs of the human body and niche. This paper will discuss two experiments conducted that exhibit the function of BMP. One experiment will examine the results of BMP deletion in genetically modified dermal papilla cells patched onto mice that had no hair. The second scientific experiment will demonstrate the effects of excess and limited quantities of BMP expression in vitro on isolated chick otic vesicles. From these experiments scientists can foresee the future in developing variousShow MoreRelatedLab Report1388 Words   |  6 PagesAbstract: Tissue regeneration through cell differentiation from one cell type to another is a phenomenon occurs in some species of fish and amphibians, however, mammals are incapable of reprogramming one cell lineage to achieve a similar result.

Essay about The Importance of the Land in Twentieth...

The Importance of the Land in Twentieth Century Irish Poetry Land in the Twentieth Century was very important to the Irish nation, and this is portrayed through the works of certain pieces of poetry, written by native countrymen Thomas Kinsella and Seamus Heaney. The poem Wormwood is expressed by Thomas Kinsella in a powerful and descriptive manner where the reader can experience the deepest thoughts of the writer, in his or her own way. The reader feels a sense of involvement as Kinsella sets the scene in the dank woods: In a thicket, among wet trees, stunned, minutely Shuddering, hearing a wooden echo escape. Kinsella informs us of a tree, which he is in fact bewildered by. How he†¦show more content†¦For instance, he may have been referring to the joining of Northern Ireland and the Southern part of the country, a very popular talking point at this period in time. Although the two parts are joined together, they attitudes are very dissimilar. As the IRA intervene, and cause even more controversy the countrys become even more separated, (the trees being separated by the axe). Between my finger and thumb The squat pen rests; snug as a gun. This quotation refers to Seamus Heaneys poem, Digging. It immediately refers to Heaneys poetical setup, but when it refers to being snug as a gun. Maybe he is letting us in to the secrets of his country and how crime and violence around the time of his work was a focal point among the citizens of Ireland. The descriptive nature of his poem brings the reader close to the poem in a sense of involvement. This is similar to Kinsellas poem which was referred to earlier. He is very proud of his family and his familys predecessors. For example he tells us of his famous Grandfather, who would work solidly and was better than any other man at his job: My Grandfather cut more turf in a day Than any other man on Toners bog. This also leads on to the point that Ireland was such a poor nation at this time, it had to work very hard to achieve what it desired. The land was a focal point for the country of Ireland and to become aShow MoreRelatedChanging Characteristics of Poetry from Modern to Romantics3272 Words   |  14 Pages Topic: Changing characteristics of poetry from Romantics to Modern Abstract: The characteristics of poetry changed with the changing of eras and literary periods.

Jealousy The Strongest Form Of Self Destruction

Maddie Fender Mrs. Monzel Period 6 17 October 2016 Jealousy: The Strongest Form of Self-Destruction In A Separate Peace by John Knowles, Gene Forrester and his best friend Phineas, or Finny, as Gene likes to call him, live and confront conflict at the all-boys boarding school of Devon during World War II. Gene and Finny possess traits that vary greatly, which cause both conflict and jealousy for both of them. A compare and contrast of Gene and Finny’s perception of self and others and their conflict management behavior reveals Knowles’ theme that jealousy lies at the heart of the creation of internal enemies. Finny and Gene both perceive themselves differently, as Gene’s insecurities draw back to internal turmoil while Finny’s humble confidence causes jealousy between the two boys and creates a force inside the soul that must be controlled. One afternoon, Finny and Gene are walking past the record board when Finny spots the record for the 50-meter freestyle and says: â€Å"I have a feeling that I can swim faster than A. Hopkins Parker† (43). Finny’s confidence appears strongly here because he immediately believes that he can swim faster than the fastest swimmer in the history of the Devon school. Because Finny automatically believes that he can beat the record, Gene becomes envious and his internal conflict and enemy within him starts to come to surface. When Finny finishes, he says that he could â€Å"hear [himself] going just a little bit faster than A.

Cecil Rhodes “Confession of Faith” free essay sample

â€Å"Confession of Faith† In Confession of Faith, the great imperialist and wealthy diamond mine owner Cecil Rhodes stresses his opinion of Britains right to conquer land in the world, and the importance of involvement by the British citizens. His beliefs were that imperialism is the key to political and economic power and shows how British nationalism led to the expansion of its territories. â€Å" It often strikes a man to inquire what is the chief good in life; to one the thought comes that it is a happy marriage, to another great wealth, and such seizes on his idea for that he more or less works for the rest of his existence. (pg. 243) Cecil Rhodes wanted nothing more than to serve his country. He believes that the Anglo-Saxon race should rule the world. â€Å"I contend that we are the finest race in the world and that the better it is for the human race. We will write a custom essay sample on Cecil Rhodes â€Å"Confession of Faith† or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page † (pg. 243) Any other race to him should not exist. Humans being born that are not going to be raised in the Anglo-Saxon race are a waste to him. He wanted to make the British Empire a superpower in which all of the white countries in the empire would be represented in the British Parliament. Why should we not form a secret society with but one object the furtherance of the British Empire and the bringing of the whole uncivilized world under British rule for the recovery of the United States for the making the Anglo-Saxon race but one Empire. † (pg. 243) Rhodes did want to breed an American elite of philosopher-kings who would have the USA rejoin the British Empire. His dream is made clear on how and why he wanted the whole world to be like the Anglo-Saxon race. Rhodes did respect the Germans and the Kaiser, but still thought his race and society was better. Rhodes made his point very clear in this excerpt and goes into detail on what other races do wrong. â€Å"It is our duty to seize every opportunity of acquiring more territory and we should keep this one idea steadily before our eyes that more territory simply means more of the Anglo-Saxon race more of the best the most human, most honourable race the world possesses. † (pg. 243) For his race, he has very high standards on how to spread this belief of his. The more land the race can acquire, the better off the race would be. To Rhodes his idea of the world turning into a one-race world is his dream. By expanding and expressing his ideas and beliefs, it would make the Anglo-Saxon race even more prevailing. â€Å"The Society should always be searching for members who might by their energies or character forward the object but the ballot and test for admittance should be severe)†¦Ã¢â‚¬  (pg. 244) Ceil Rhodes was a very powerful and wealthy man in his time. He was one of the wealthiest men in the world. I think since he had so much wealth it made him come to the conclusion he could control the world and make it a one-race society. I would compare Rhodes to an earlier Adolph Hitler, with trying to succeed a one-race dominance. Rhodes has too much of a racists mind for me. God is the only creator in race, and Rhodes trying to be God is a disgrace to mankind. All races are different in there own way and have the right to live wherever they please.
