“Stem cells are undifferentiated, primitive cells with the ability both to multiply and to differentiate into specific kinds of cells. Stem cells hold the promise of allowing researchers to grow specialized cells or tissue, which could be used to treat injuries or disease (e.g., spinal cord injuries, Parkinson’s disease, Alzheimer’s disease, diabetes, strokes, burns).” (Slevin, 2010)

Apply the scientific method to the information included within the scenario and develop a null and a research hypothesis based on it. Using the hypotheses you have developed, compare the characteristics of the different experimental research designs discussed in the Skidmore (2008) article and choose the one that is most appropriate to adequately test your hypotheses. Identify potential internal threats to validity and explain how you might mitigate these threats. Apply ethical principles to the proposed research and describe the implications of this type of research in terms of the population(s) and cultural consideration(s) represented in the sample(s) within the scenario.
