One body part most people don’t classify as organs are bones. Bones grow and develop throughout a human’s entire life. In that time, bones can fracture and break. After a fracture, a bone repairs itself through a process similar to that involved in its formation. Our understanding of this healing process has evolved over time through extensive research, some of which has led to surprising discoveries. For example, bones have been found to be one of few tissues that can repair itself without forming scars (Marsell and Einhorn 2011). In this paper, we will discuss the process of human bone reparation and recent advances in this field, specifically about bone grafts and stem cell research. Bone reparation begins with a fracture of the osseous…
research) There are many different uses for stem cells, and different stem cells which can do things other stem cells can and can do. There are two main stem cells, and they the embryonic stem cells, and adult stem cells. However there ae about another dozen more stem cells which are also important to the human body. These other stem cells are tissue stem cells, blood stem cells, skin stem cells, Mesenchymal stem cells, stem cells in the eye, induced plum stem cells, brain stem cells, bone…
STEM CELLS Stem cells are very homogenous due to the fact that they are of the same family type or lineage characteristically speaking. They are differentiated from other cells by two features. The first feature is that they are able to divide by cell division and the second feature is that under specific experimental conditions they can be directed to become tissue cells with certain functions. Stem cells are able to transform or regenerate themselves growing into the body’s approximately 200…
Regenerative Capabilities of Dental Stem Cells Introduction – state hypothesis or problem and its scope (<1 page) Regenerative medicine aims to restore or establish normal function by replacing or regenerating human cells, tissue, or organs (Dunnill). Cell-based therapies are integral in regenerative medicine for the inherent ability of stem cells (SCs) to differentiate into specific cell types (Sedgley & Botero). SCs can be isolated during embryogenesis (embryonic SCs), or in postnatal…
According to Stem Cell Reviews, it is estimated that as many as 128M individuals in the United States, or 1 in 3 people might benefit from regenerative medicine. Those statistics are eye-opening for the nurse life care planner because regenerative medicine will eventually become a viable treatment modality for so many of those individuals with whom the nurse life care planner is called upon to assist with preparation of a future care plan. Regenerative medicine is the process of creating…
breakthrough in 2006 where scientists had discovered a way to genetically reprogram mouse mature cells to convert them into a cell that has embryonic stem cell properties and these cells were named ‘induced pluripotent stem cells’ although it is still undetermined whether this new stem cell and embryonic stem cells are critically different. Human induced pluripotent stem cells were developed a year later in 2007. Scientists are optimistic about these stem cells and they are now being used within…
Stem Cells One of the biggest ethical and scientific debates in the scientific communities involves Stem Cell research. Stem cells are cells with the ability to develop into different types of cells in the body. They can serve as a type of internal repair system for the body. They are distinguished from other cells because they are unspecialized and are capable of renewing themselves through cell division. Also, under physiologic or experimental conditions they can be induced to become tissue…
Stem cell based treatment of neurodegenerative diseases The world of stem cells is extraordinary as they can differentiate into different types of cells and they come in different types of stages. stem cells can help with further treatments and research for cures. Embryonic stem cells which are the first stage of a stem cell are only around for a few days whilst in the embryo, then comes the adult cells in particularly mesenchymal stem cells that can be found in bone marrow or other particular…
A cell is the smallest structural and functional unit of an organism. Stem cells are undifferentiated cells. “The essential characteristics of [these] cells are their ability for self-renewal and the ability to form one or more specialised cell types over time” (Carvalho and Ramalho-Santos 596). In other words, they serve as an internal repair system. When a stem cell divides, each new cell can either remain a stem cell or any other type of cell with a normal yet more specialized and…
Stem cells are cells that have the ability to self-renew and differentiate to become a myriad of different cell types. They serve as an internal repair system, with the purpose of replenishing or damaged cells. They can be found in various microenvironments within the tissues called stem cell niches cells, some examples of these include include the brain, bone marrow, blood vessels, skin, teeth, heart, amniotic fluid, umbilical cord, etc. Typically, there are only a small number of stem cells in…
