Hematopoietic Stem Cell Transplant (HSCT) Exam 2023/2024 what is HSCT? - ANSWER--procedure in which stem cells made in the bone marrow are collected, either from a donor or from the transplant patient and stored -patient then receives chemo +/- radiation therapy -collected stem cells are then infused into the patient's blood stream to restart their stem-cell production and function autologous HSCT - ANSWER-patient donates own Hematopoietic Stem cells allogeneic HSCT - ANSWER-relat...

What is credited with coining the term cancer - Hippocrates What factors contribute to immortalization/proliferation of cancer cells - Anchorage-independent growth, inhibition of apoptosis, and tumor-suppressor inactivation can all contribute to immortalization/proliferation of cancer cells Cancer cells can avoid growth and invasion restrictions imposed by the immune system by - producing a heterogeneous group of cells, producing molecules that inhibit T lymphocyte function, surrounding th...

CELL TRANSPORT AND HOMEOSTASIS QUESTIONS AND ANSWERS A+ Homeostasis - ANS-the need of an organism to maintain and regulate constant or stable internal conditions Negative feedback - ANS-a cell responds opposite of the initial change. The output is decreased or inhibited. Positive feedback - ANS-a cell amplifies the initial change. Promotes change instead of reversing to speed up the effect. Phospholipid - ANS-cell membrane structure. made up of a polar hydrophilic head and a nonpo...

Passive Transport - Answer molecules move with the concentration gradient from high to low concentration NO energy required. Diffusion - Answer Movement of MOLECULES from area of high concentration to an area of low concentration. (small molecules move this way) Osmosis - Answer Diffusion of WATER through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal. Hypertonic solution - Answer ...

cell membrane - Answer Serves as the cell's boundary from its environment. Proteins - Answer The channels and pumps that help move materials from one side of the cell membrane or the other are made of _______. cell membrane - Answer regulates the movement of materials into and out of the cell active transport - Answer requires the input of energy from the cell diffusion - Answer occurs because molecules constantly move and collide with each other Stop moving - An...
