Tissue Engineering Essays - 2773 Words

Tissue Engineering Tissue engineering, labeled by Time.com as the number one hottest job for the 21st century, holds great potential for medicine and the treatment of chronic diseases and disorders. With tissue engineering, familiar problems like the rejection of foreign tissue by the body, the severe shortage of organ donors, and the inefficiency of artificial devices may be solved. However, this cutting edge biotechnology has already spurred intense controversy over the ethics and morality of creating spare human body parts. The goal of tissue engineering is to grow tissues and neo-organs that can be used for transplants. Tissue engineers must first decide what type of cell they want to use and stimulate to grow. Because animal†¦show more content†¦In addition to giving the growing cells a shape to grow into, the scaffold distributes the cells about 2-3 mm apart and allows the cells better access to nutrients and means of waste removal, which is important when trying to grow an evenly distributed functioning organ. For larger, solid organs, such as the liver, pancreas, and kidneys, blood vessels need to be created so the organs have adequate blood supply. By covering the engineered organs with growth factors, angiogenesis, the formation of new vasculature, can be prompted. Although tissue engineers and researchers have already succeeded with creating new skin, blood vessels, bone and cartilage, the more complex organs are difficult to reproduce because of their different functions. Researchers must also be concerned with the mechanisms of growing the tissue. For instance, the advantages and disadvantages are not yet clear for the length of time the cells should be exposed to the growth factors or the difference between growing the tissue outside the body or implanting the scaffold inside the body and letting the tissue grow there. Scaffolding and injectable polymers that form scaffolds in irregular areas (like bone fractures) are also being improved. Much more research is being conducted in order to grow the hearts, livers, breasts, kidneys, and other valuable organs that so many people need. Although tissue engineering has great application for helping ill patients, itShow MoreRelatedTissue Engineering Research 1371 Words   |  5 Pagestransplant (National Kidney Foundation). These numbers cannot be ignored because blindness only results in loss of life. Currently, alternatives, such as mechanical devices and artificial prostheses, don’t repair tissue or organ functions because they are not intended for integrating host tissues, and if these alternatives are used for long-term implantation, the recipient could suffer from an inflammatory response (Chapekar). For illnesses such as end-stage liver disease, the only successful treatmentRead MoreHistory of Injectable Tissue Engineering1656 Words   |  7 PagesInjectable Tissue Engineering INJECTABLE TISSUE ENGINEERING My part of the assignment is to provide a detailed history of Injectable Tissue Engineering. I must also provide details how Injectable Tissue Engineering affects the environment. Ttissue engineering has advanced dramatically in the last 10 years, offering the potential for regenerating almost every tissue and organ of the human body.

Tissue engineering and tooth regeneration offer solutions to the problems of tooth, bone, and tissue loss, all of which are major global problems. Although the field of tissue engineering is continuously advancing, it still faces aRead MoreThe Effect Of Scaffolds On Bone Tissue Engineering1165 Words   |  5 PagesDevelopment of scaffolds plays a vital role in bone tissue engineering in order to repair, regenerate tissues by mimicking of natural bone extracellular matrixes. Considering that bone is a composite of minerals and proteins, it is preferred to develop a composite that mimics natural bone. The ideal nanocomposite materials should have biocompatibility, suitable mechanical and antimicrobial properties, nontoxicity and surface functionality to favor cell proliferation.1,2 Many organic-inorganic materialsRead MoreTissue Engineering in Replace of Organ Donation1353 Words   |  5 Pagesorgans or tissue with a functioning substitute, organ transplantation offers an immediate cure. Unfortunately, this â€Å"cure† is never guaranteed because of the high risk of graft rejection and that’s if a suitable donor can be found. Thus, tissue engineering has been the projected new treatment for these problems. Tissue engineering replaces the diseased or damaged tissue or organs with biofabricated counterparts made using the specifications dictated by the features of the specific tissue or organRead MoreMechanical Properties Of Bone Tissue Engineering1974 Words   |  8 PagesUsed in Bone Tissue Engineering: A Review Study Parag Borulkar(Student)*1,Mr.V .L.

In this paper we are going to study three basic bone tissue replacementsRead MoreThe Importance Of Tissue Engineering And Human Clinical Trials1252 Words   |  6 PagesTissue engineering has been an opportunity to restore the human condition from wounded to whole through the combination of biological, biochemical, and biomechanical concepts. Unlike traditional transplantation, tissue engineering and regenerative medicine uses a patient’s own cells to fabricate new tissues which are then grafted back into his or her body. Of course, the goal is to apply the practices in the lab to the general public and to develop a new and more effective means to treat patientsRead MoreNanotechnology And Its Effects On The Field Of Drug Delivery And Tissue Engineering2173 Words   |  9 Pageshas attracted a great deal of attention in the field of drug delivery and tissue engineering over the past few decades. This increasing interest in nanomedicine is driven by its potential to revolutionize the treatment of some prevalent global disease such as cancer, cardiovascular disorders, rheumatoid arthritis, osteoarthritis, and diabetes in safer and more effective ways [1, 2].

Unfortunately, nothing would have been done to make his appearance more appealing to the eye. That is, until we entered the age of bioengineering. By definition, biomedical engineering, or more affectionately known as bioengineering, is the use of engineering philosophies in correlation with the fields of biology and health care. It
