Bio-Leonhardt is an American company that specializes in bioelectric stimulation sequences to reverse fibrosis and convert scar tissue into new beating heart muscle. The company has patented bioelectric signal sequences for stem cell differentiation and follistatin expression, which are key to managing and recovering from advanced heart failure. The company's platform technology components include a bioelectric stimulator, signals and sequences for precise control of regeneration promoting proteins, and a patented stem cell differentiation into heart muscle signal within myocardial scar tissue. The company also has a patent-pending angiogenic bioelectric signal sequence for mature new blood vessel growth and a real-time inflammation reading and management sequence. The company's products are in early stage development and are not yet proven safe or effective in statistically significant controlled clinical studies. The company was founded by Stuart Williams, and the CEO is Howard J. Leonhardt.

Stem Cell Bra is an American company that is currently in the pre-clinical testing stage of developing a bra that uses stem cells from a woman's own fat tissue and bone marrow to possibly increase breast size by one cup over a period of 12 weeks. The stem cell bra has shown promising results in a pilot feasibility clinical study conducted in Spain in 2021, with 1/3 of the enrollees experiencing a one cup size increase, 1/3 experiencing a 10% increase, and 1/3 experiencing no change. The company has gathered safety data on 15 sheep and cows with excellent results, showing an increase in breast fullness volume ranging from 20 to 30% and true new breast tissue formation. The company has over 150 USPTO patent and patent pending claims on bioelectric regeneration methods and devices. However, the company cautions that the product is only available in countries where clinical studies have been approved by regulatory authorities and is not yet proven safe or effective in statistically significant controlled clinical studies. The company was founded by Howard J. Leonhardt, who has been the CEO since incorporation.
