Developmental biology

because they make up tissue, which develops into an organism (What Is a Cell?). These organisms include humans and humans study cells in order to fix physical damage done to the human body and create cures for diseases, and disabilities (Why Cell Biology is So Important?). Therefore, cell research provides medical benefits, but it also creates a rising dilemma occurring presently in medical science, where a patient’s cells are being taken without his or her consent. This problem is further…

Epigenetics is defined as the study of changes in organisms resulting from modifications in gene expressions.The use of stem cells prove to be a vital part in the course of Epigenetics.Stem cells are characterized by two traits. They are self-renewal, able to divide into more identical cells and pluripotency, which allow the cells to become any kind of cell such as Erthrocyte or osteoclast.The relationship between epignetics and stem cells paved a pathway to an experiment relating to the…

My first research experience started when I participated in bone scaffold designing project at the Cooper Union in Spring 2012, under the supervision of professor David Wootton at Cooper Union Department of Mechanical Engineering. The purpose of this study was to design and manufacture bone scaffold for orthopedic trauma, especially for segmented bone fracture. I worked with a senior mechanical engineering student who had been conducting the research as his senior capstone project. The first…

Duplicate Copy Human cloning is a rather controversial subject that has passionate people on both sides of the debate. It’s a technology that some feel questions their ethical standings and hits a little too close to home. On the other hand, human cloning could also provide medical answers to some incurable diseases, birth defects, and genetic disorders that currently have no treatments. Necessary sacrifices must be made for advancements in science to produce results. Many people claim that…

Upon development, the nervous system wires itself completely – an impressive feat considering the millions of connections and neurons in the body. However perhaps even more impressive is the ability of the nervous system to restore neuronal connections after injury. This is particularly advanced in frogs, fish and invertebrates as once an axon is cut in the central nervous system, the regeneration allows full functional recovery whereas in the mammalian central nervous system full recovery is…

Stem cells are truly the stem of our existence saying how these microscopic cells have an astronomical job. Ever since we were all embryos, we’ve had stem cells, specifically embryonic and adult stem cells. Many factors tie into the world of stem cells such as what and where they came from, the research done on stem cells, and the legislation along with my personal opinion on the research. There are two characteristics that separate stem cells from other cells, one is that they are unspecialized…

Picture this, your best friend is rushed to the hospital due to him/her being involve in a car accident. It is later found out that your friend in in dire need of a new lung in order to survive. Frantically, you're willing to donate one of yours as a means to save your friend life. Only, there is one problem; your lung is not compatible with your friends. There is one potential way to save your friends life, through the use of stem cells. We are on the verge of a major scientific and medical…

Discussion Dugesia regeneration is happening and the response rate to stimuli can be observed. Planarians have the ability to fully regenerate demonstrating the fascinating study of stem cells and tissue regenerations. The regeneration of the planarian may require the planarian to reshape its form by finding the right proportion to acquire the right shape and size of its body to form a functional, bilaterally symmetrical anatomy. The regeneration period can vary with different species, some…

can be repaired: direct bone healing is when the bones are intervened and set into place to allow for repair, indirect bone healing is allowing the fracture to heal naturally without any intervention from a third party. This paper will review the biology of a fracture and how stem cells and ossification processes coordinate with indirect and direct fracture healing of the bone. ______________________________________________________________________________ Introduction Bone is a living tissue…

Some people believe that cloning is a good thing and some people think it’s a bad thing. “Critics warned that the technology brought with it a high risk of miscarriage and stillbirth (born full-term dead) and for those creatures that did survive, ill health and premature death.” “Doctors hope to use cloning technology to generate stem cells from patients that can then be used to repair damaged parts of the heart, liver, lungs, brain or other vital organs in illness ranging from cardiovascular…
