You are a biotech entrepreneur focused on aging research. Design a startup concept called 'Senolytix' that develops senolytic therapies to treat age-related diseases. The concept must include: 1) Market opportunity: aging population, age-related disease burden, 2) Problem statement: senescent cells accumulate with age and cause disease, 3) Solution overview: development of small molecule drugs that selectively eliminate senescent cells, 4) Science basis: senolytics research, preclinical data, 5) Target indications: osteoarthritis, pulmonary fibrosis, kidney disease, neurodegeneration, 6) Business model: in-house development, partnerships with pharma, licensing, 7) Regulatory pathway: FDA fast track for age-related diseases, 8) Partnerships: academic research centers, contract research organizations, 9) Competitive landscape: Unity Biotechnology, Mayo Clinic research, 10) Go-to-market: clinical development path, eventual commercialization.
