Infusion of tissue containing undifferentiated blood cells from bone marrow is?
Bone marrow transplantation is a medical procedure where tissue containing undifferentiated blood cells from bone marrow is infused into a patient to replace damaged or destroyed bone marrow. This procedure is often used in the treatment of certain cancers, such as leukemia.
How could you develop a procedure to identify cancerous tissue by counting the number of cells undergoing mitosis?
To develop a procedure to identify cancerous tissue based on the number of cells undergoing mitosis, you could obtain a tissue sample, stain it to highlight mitotic cells, and then count the number of cells undergoing mitosis per unit area using a microscope. An increased number of cells undergoing mitosis may indicate abnormal cell proliferation characteristic of cancer. Further validation through histological analysis and comparison with healthy tissue samples would be necessary to confirm the presence of cancer.
What is the purpose of crystal violet in the Gram's stain procedure?
Crystal violet is the primary stain in the Gram's stain procedure, used to color all bacteria cells purple. This helps differentiate between Gram-positive bacteria (which retain the violet color) and Gram-negative bacteria (which lose the violet color when decolorized with alcohol).
How did doctors harvest and culture cells from Henrietta Lacks?
Doctors harvested cells from Henrietta Lacks by taking a small tissue sample from her cervix without her consent during a medical procedure. The cells were then cultured in a laboratory setting by providing them with the necessary nutrients and environment to multiply and grow continuously, becoming the famous HeLa cell line.
What is a stem cell transplant?
A stem cell transplant involves replacing damaged or diseased bone marrow with healthy stem cells to restore the body's ability to produce healthy blood cells. This procedure is used to treat certain cancers, such as leukemia and lymphoma, as well as other blood disorders. The healthy stem cells can be obtained from a donor or from the patient themselves.
When copying or moving cells if data already exists in the destination cells?
will not complete the copy or move procedure
What procedure usually precedes a cone biopsy?
The procedure is often recommended if a Pap test indicates the presence of abnormal cells.
What happens to the cells destroyed in the cervical cryotherapy procedure?
The cells destroyed by freezing are shed afterwards in a heavy watery discharge.
How biologist get DNA out of the cell?
DNA can be extracted from most cells by a simple chemical procedure: the cells are opened and the DNA is separated from the other cell parts.
How does the bodys cells take up oxygen and unload carbon dioxide?
because it is a tactical procedure
How are cancer cells killed in a RFA procedure?
When the electrode has been properly placed, a radiofrequency current is passed through it, heating the tumor and killing the cancer cells.
What is the Edmonton islet cell transplant procedure?
Innovations in islet cell transplants, a procedure that involves transplanting a culture of the insulin-producing islet cells of a healthy pancreas to a patient with type I diabetes, have increased the frequency of this procedure.
How does the pallidotomy procedure mimic the effect of dopamine?
Pallidotomy mimics this action by permanently destroying the GPi cells.
What is the islet cell transplantation procedure?
Innovations in islet cell transplants, a procedure that involves transplanting a culture of the insulin-producing islet cells of a healthy pancreas to a patient with type I diabetes.
What is the significance of differential centrifugation?
differential centrifugation is a common procedure in microbiology and cytology used to separate certain organelles from whole cells for further analysis of specific parts of the cells.
What is plasmapheresis?
Plasmapheresis is a process in which the plasma is separated from the blood cells. People with autoimmune diseases are sometimes treated with this procedure. The plasma is disposed of and the cells are reintroduced to the body with other fluids.
What is the process of plasmapheresis?
The basic procedure consists of removal of blood, separation of blood cells from plasma, and return of these blood cells to the body's circulation, diluted with fresh plasma or a substitute.
