About Tempo Bio

Aiming to provide high-quality biotech ingredients for the personal care industry

Founded in 2013, Tempo Bioscience (Tempo) develops and provides human stem cells, stem cell–derived products, and assay solutions to scientists in academia, nonprofit research, biotechnology, pharmaceutical, and Personal Care organizations. Tempo’s technologies have been cited in peer‑reviewed studies and recognized by PharmaTech Outlook in 2018 and 2021. Partnering with more than 1,000 academic institutions, venture‑backed biotech companies, multinational biopharmaceutical organizations, and leading Personal Care companies, Tempo remains focused on innovative products that support scientists worldwide.

What are exosomes? And what makes them special?

Exosomes are tiny, membrane‑bound particles naturally released by human cells. These nanoscale vesicles carry growth factors, peptides, and other bioactive molecules that help support cellular health and function.

By transferring this molecular “cargo” between cells, exosomes enable cell‑to‑cell communication and help coordinate key biological processes. This signaling activity is closely linked to the body’s natural pathways for repair, renewal, and maintenance of tissues.

At Tempo, we focus on exosomes released by defined subtypes of human stem cells to study and harness their distinct biological properties. This work opens the door to innovative product concepts for anti‑aging, repair, and regeneration‑focused applications. Across multiple fields, including wound care, aesthetic medicine, and hair science. Exosomes are increasingly being explored for their potential roles in next‑generation ingredients.

Evolution of Exosome Science

Exosomes, a class of extracellular vesicles (EVs), were first characterized roughly 30 years ago as small, cell-derived membrane structures released into the extracellular space. They are generated through two main routes: by fusion of intracellular endosomes with the cell surface, and by direct budding from the plasma membrane as microvesicles.

Since their discovery, exosomes have moved from a biological curiosity to a central focus of cell‑communication research. Studies now show that EVs form a sophisticated signaling network, transferring lipids, proteins, and nucleic acids (including DNA, RNA, and microRNA) between cells.

For formulators, this evolving science positions exosomes as an emerging class of bio‑inspired, information‑rich ingredients that are compatible with human skin, creating new opportunities for differentiated, next‑generation product concepts in Personal Care.
