Beyond therapeutics, the company also develops, manufactures, and commercializes anti-aging skincare products and an extensive range of human cell culture products. Its diverse portfolio of human cell culture products serves as vital research tools across numerous scientific disciplines. This includes specialized cells and reagents designed for studying: Dermatology: Skin diseases, toxicology, and wound healing. Cardiovascular & Oncology: Heart and blood vessel conditions, and various cancers. Respiratory: Bronchial and tracheal conditions, toxicity, cystic fibrosis, asthma, and pathogenesis. Reproductive & Urological: Prostate, renal, bladder, corneal, and female reproductive system diseases, as well as general cellular physiology. Musculoskeletal & Metabolic: Skeletal muscle biology, diabetes, insulin pathways, muscle repair, and myotube development. The company also provides adult stem cells for regenerative medicine research and a full complement of reagents and supplements essential for cell growth, staining, and cryopreservation. Distribution of ISCO's skincare range occurs via its website and specialized professional channels, while its human cell culture products reach customers through a dedicated sales force, original equipment manufacturer (OEM) partners, and authorized brand distributors.
