PRP and Prolotherapy are individual treatments that were even suggested and used in combination with stem cell therapies. Prolotherapy predates PRP as a chemical irritant therapy originally used to sclerose tissues. Prolotherapy is meant to stimulate platelet derived growth factors release to improve tissue healing response. Prolotherapy shows negligible efficacy improvements over corticosteroids, but may have underlying side effects from being an irritant. PRP is a more modern therapy for improved healing. Speculations state initial use was in an open heart surgery to improve healing post-surgery. PRP is created via centrifugation of patient blood to isolate growth factors by removing serum and other biological components to increase platelet concentration. PRP is comparable to corticosteroid injections in efficacy, but as an autologous application, there are no side effects making it more advantageous. Growth factors induce healing response and reduce inflammation. Growth factors stimulate cell growth, proliferation, differentiation, and stimulate cellular response mechanism such as angiogenesis and mitogenesis. The growth factor stimulation of PRP and prolotherapy both assist stem cell proliferation. Additional research is needed to determine differential capacity to ensure multipotent stem cells regenerate the correct cell type from the increased differential capacity offered by growth factor recruitment. The application of combination therapy for stem cells is unsubstantiated and applications violate FDA ‘minimal manipulation’ guidelines.
It is in this context that this dissertation, informed by critical disability studies and feminist science and technology studies, examines the understanding and enactment of disability and responsibility in relation to biomedical technologies. I draw from qualitative empirical data from three distinct case studies, each focused on a different biomedical technology: prenatal genetic screening and diagnosis, deep brain stimulation, and do-it-yourself artificial pancreas systems. Analyzing semi-structured interviews and primary documents through an inductive framework that takes up elements of Grounded Theory and hermeneutic phenomenology, this research demonstrates a series of tensions. As disability becomes increasingly associated with discrete biological characteristics and medical professionals claim a growing authority over disabled bodyminds, users of these technologies are caught in a double bind of personal responsibility and epistemic invalidation. Technologies, however, do not occupy either exclusively oppressive or liberatory roles. Rather, they are used with full acknowledgement of their role in perpetuating medical authority and neoliberal paradigms as well as their individual benefit. Experiential and embodied knowledge, particular when in tension with clinical knowledge, is invalidated as a transgression of expert authority. To reject these invalidations, communities cohering around subaltern knowledges emerge in resistance to the mismatched priorities and expectations of medical authority, creating space for alternative disabled imaginaries.
Industries and research utilizing genetically-engineered organisms are often subject to strict containment requirements such as physical isolation or specialized equipment to prevent an unintended escape. A relatively new field of research looks for ways to engineer intrinsic containment techniques- genetic safeguards that prevent an organism from surviving outside of specific conditions. As interest in this field has grown over the last few decades, researchers in molecular and synthetic biology have discovered many novel ways to accomplish this containment, but the current literature faces some ambiguity and overlap in the ways they describe various biocontainment methods. Additionally, the way publications report the robustness of the techniques they test is inconsistent, making it uncertain how regulators could assess the safety and efficacy of these methods if they are eventually to be used in practical, consumer applications. This project organizes and clarifies the descriptions of these techniques within an interactive flowchart, linking to definitions and references to publications on each within an Excel table. For each reference, variables such as the containment approach, testing methods, and results reported are compiled, to illustrate the varying degrees to which these techniques are tested.
