Ex-3D Systems Exec Launches Startup for Regenerative Breast Tissue

After a 17-year tenure at 3D Systems, Katie Weimer has launched a new startup, Genesis Tissue, to advance a project focused on regenerative breast tissue. Weimer took over the initiative when it faced the possibility of being discontinued within her previous company, citing the need for focused investment and agility that is challenging to achieve in a large corporate environment. She had been involved with the regenerative breast tissue project since 2021 and felt compelled to ensure its continuation due to her belief in its mission.

The Colorado-based startup is developing a 3D printed scaffold designed to facilitate the regeneration of a patient's own breast tissue following cancer surgery. This approach aims to move away from permanent implants, offering a potentially superior alternative for breast reconstruction. Weimer’s personal motivation stems from losing her mother to breast cancer, which fueled her interest in regenerative medicine and breast reconstruction.

Genesis Tissue's technology involves implanting a patient-specific scaffold after tumor removal. This scaffold is then filled with the patient's own harvested fat tissue, which contains stem cells and other regenerative components. The scaffold is designed to degrade over time as the patient's body utilizes the fat to form new tissue, effectively using the body as a "bioreactor" to grow healthy tissue in place of a foreign implant.

While acknowledging that silicone implants are currently the standard for many reconstruction procedures, accounting for a significant majority of implants used annually, Weimer highlights their limitations. She points out that approximately one-third of breast implants develop complications, leading to tens of thousands being removed each year. These implants have a finite lifespan, carry FDA warnings, and are not designed for permanent use, suggesting a significant need for improved solutions.

Weimer's background in additive manufacturing for healthcare applications, including her time at 3D Systems and its predecessor Medical Modeling, provided a strong foundation for this venture. Her expertise was further enhanced by her pursuit of a PhD in bioengineering at Colorado State University, where she collaborated with researchers in tissue engineering and regenerative medicine, deepening her understanding of cellular and biological processes.
