- Discuss how immunohistochemical techniques can identify and label the epithelial cells that may be useful in cancer biopsyA question that puzzled scientists was that how chemical carcinogens caused cancer. The experiment given below was done to solve this question. Explain the experiment done and its conclusion. formation of a focus of morphologically transformed cells normal chemically transformed mouse fibroblasts DNA DNA - injection of morphologically transformed cells into mouse fibroblasts transfection using calcium phosphate co-precipitation procedure mouse host tumor Figure 4.1 The Biology of Cancer (O Garland Science 2014) HEFollowing is the data and notice that it is a terrible idea to culture hMSCs longer than 10 days.

The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…
- are best suited for diagnosing a disorder that is caused by low protein expression due to unwanted DNA methylation. Biochemical tests Molecular tests Cytogenic tests Carrier tests Drug testsWhy won’t in vitro results necessarily ensure clinical successFigure 17.15 In 2011, the United States Preventative Services Task Force recommended against using the PSA test to screen healthy men for prostate cancer. Their recommendation is based on evidence that screening does not reduce the risk of death from prostate cancer. Prostate cancer often develops very slowly and does not cause problems, while the cancer treatment can have severe side effects. The PCA3 test is considered to be more accurate, but screening may still result in men who would not have been harmed by the cancer itself suffering side effects from treatment. What do you think? Should all healthy men be screened for prostate cancer using the PCA3 or PSA test? Should people in general be screened to find out if they have a genetic risk for cancer or other diseases?
- Organ Transplants Must Be Immunologically A couple has a young child who needs a bone marrow transplant. They propose that preimplantation screening be done on several embryos fertilized in vitro to find a match for their child. a. What do they need to match in this transplant procedure? b. The couple proposes that the matching embryo be transplanted to the mothers uterus and serve as a bone marrow donor when old enough. What are the ethical issues involved in this proposal?You are in charge of a new gene therapy clinic. Two cases have been referred to you for review and possible therapy. Case 1. A mutation in the promoter of a proto-oncogene causes the gene to make too much of its normal product, a receptor protein that promotes cell division. The uncontrolled cell division has caused cancer. Case 2. A mutation in an exon of a tumor-suppressor gene makes this gene nonfunctional. The product of this gene normally suppresses cell division. The mutant gene cannot suppress cell division, and this has led to cancer. What treatment options can you suggest for each case?Benign tumors: a. are noncancerous growths that do not spread to other tissues b. do not contain mutations c. are malignant and clonal in origin d. metastasize to other tissues e. none of these
