References Lecture notes (hyperlink) Activity notes (hyperlink) More links… Clinical Trials Advanced Cell Technology 1)Terminally differentiated cells made from human embryonic stem cells. Retinal pigment epithelial cells for Stargardt’s Macular Dystrophy and macular degeneration. 2)Animal studies = no tumors. 3)Detection sensitivity less than 1:1,000,000 cells (in vitro=in vivo?) 4)50,000 cells per transplant 5)Twelve patients enrolled, none transplanted

References Lecture notes (hyperlink) Activity notes (hyperlink) More links… Clinical Trials Stem Cells Inc. 1)Neural cells made from fetal neural stem cells for Batten Disease, a fatal condition with cognitive disorders. Bore holes into the skull, into which stem cells are injected. 2)Subjects for the trial were children pre-teen and younger, raising issues about informed consent and expectations of benefit in a safety trial. 3)Such trials for patients must not be “greater than minimal risk”. Placebos in high-risk trials are controversial, so-called “sham surgeries”. 4)Six patients enrolled, one died from disease progression. Trial terminated in April because of lack of enrollment in Phase 1b.

Must have procedure between 7 and 14 days of administration. 50,000 people suffer spinal injuries every year in US 3)2,000,000 cells administered. 4)Three procedures: Stabilize the injury at a trauma center, receive the transplant, undergo intensive physical therapy

References Lecture notes (hyperlink) Activity notes (hyperlink) More links… Clinical Trials: Heart Disease
11
References Lecture notes (hyperlink) Activity notes (hyperlink) More links… Diseases of heart muscle tissue Diseases of cardiac muscles Congestive heart failure, or ineffective pumping due to cardiomyocyte dysfunction, affects 4.8 million people in U.S. Heart attack, also known as myocardial infarction Heart arrhythmias, or abnormal activity (palpitations) 1% of live births display a congenital heart defect

Science Understanding: Use accurate scientific vocabulary, facts, and concepts; present information to support argument both scientifically, ethically, and socially; understand implications of science policy Logic & Reasoning: Give arguments with sound reasoning; draw on references from assigned readings and research; use strong concise points, use supporting evidence; interpret evidence correctly; address challenges with counter arguments 19
