Heart disease claims more lives than any other illness, marking a dire need for viable heart transplants. Yet, the sheer demand for donor hearts outstrips the supply, burdened further by complications such as organ rejection and the continuous need for immunosuppressive drugs post-transplant. Dr. Doris Taylor's pioneering endeavor in engineering bioartificial hearts addresses not just a medical unmet need, but a systemic inequality in transplant accessibility and the encompassing physical, emotional, and financial toll on recipients.

In this inspiring episode of Back of the Napkin, Doris shares her extraordinary journey to becoming a pioneering scientist at the forefront of regenerative medicine.

Doris delves into her personal life, revealing her compelling motivation behind pursuing a career in science. The intersectionality of her life’s experiences has contributed to a more compassionate scientific inquiry, one that resonates deeply with those waiting on the fringes of hope for a life-saving intervention. It is not only the hearts she seeks to build in the lab that embody this sentiment, but also the metaphorical 'building heart' — the cultivation of courage, empathy, and resilience — that she instills in everyone she encounters.

A key part of the conversation focuses on Doris's groundbreaking work in creating the first beating bioartificial heart, which holds the promise of revolutionizing transplant medicine.

Key Takeaways:

• Dr. Doris Taylor’s work in regenerative medicine has led to the development of the first beating bioartificial heart, a potential game-changer for transplant medicine.
• Cardiovascular disease is a leading cause of death worldwide, and Doris's efforts aim to address the significant unmet need for donor hearts.
• The process of creating a bioartificial heart involves decellularizing a donor heart to create a "ghost heart" scaffold, which is then repopulated with cells tailored to the recipient. Doris's personal challenges, including being an LGBTQ individual in academia and dealing with professional hardships, provide an impactful narrative of perseverance and resilience.
• Organamet Bio, founded by Doris, is aiming to commercialize the technology to manufacture patient-specific bioartificial hearts, which currently estimates a cost of $300 to $500 million to reach the first human trials.

Laura Kiessling is the Novartis Professor of Chemistry at Massachusetts Institute of Technology (MIT). In this episode of Back of the Napkin, beginning in Laura's art-adorned office at MIT, the conversation explores her journey from a small Wisconsin town to the pinnacles of scientific research and education at MIT.

Laura's professional trajectory is a testament to her passion for science — from her top performance in a university chemistry class to her inspired transfer to MIT following a serendipitous spring break encounter with women doing amazing science in Boston. Her curiosity about the unknown and desire to push boundaries in chemistry led her to explore the intricate world of carbohydrates and their profound impact on diseases such as tuberculosis. 

Laura has advised approximately 100 graduate students and postdoctorates and emphasizes that the essence of scientific progress is distilled not only through individual brilliance but also through the profound impact of community, collaboration, and mentorship. Laura is not only a proponent but a role model for women in science, advocating for equal representation, mentorship, and recognition. Her narrative is punctuated with instances where she challenged the norms and paved the way for others to follow.
