Our projects
The need
Pluripotent stem cells (either IPSCs or ESCs) and their tremendous capacity to differentiate to a number of tissues are the holly grail for Regenerative Medicine. Nevertheless, the success of those differentiation protocols is still limited by the insufficient potential of stem cells to survive under challenging conditions, differentiate and maturate to be functional and maintain those properties in the long-term.

Our first approach
During my last years as senior postdoc, I established the bases of a novel technology that potentiates the differentiation capacity of stem cells. Our team described a method mainly based on the transient exposure to a microRNA that notably enhances the developmental capacity of stem cells (Salazar-Roa et al., 2020)

Building novel strategies
With this backup, we aim to design now novel technologies to significantly improve the stem potential of the initial material, their survival and their capacity to specialize into mature and functional cells.
Such strategies will reinforce the use of stem cell approaches on fundamental research, generation of disease models and numerous applications in regenerative medicines.

Advanced Differentiation Therapy in Type 1 Diabetes
Type 1 Diabetes is one of those diseases that would benefit from regenerative approaches. T1D is devastating, has no cure and can be only managed using lifelong insulin injections. Although promising, regenerative therapies are still showing a number of limitations, specially related to the maturity and survival of the obtained pancreatic cells.
Supported by La Caixa Foundation, MIT LinQ and Global CoCreation Lab, we aim to use our novel technology to generate MImoPancreas, with mature and functional cells able to efficiently produce insulin in response to glucose and with high survival rates. This strategy may represent an encouraging solution to revolutionize the current state-of-the-art for pancreatic cell replacement.

Advanced Differentiation Therapy in cancer
During my work as senior postdoc, we demonstrated how this miRNA exerts a dual role on the reprogramming/differentiation balance, acting as (i) a potent driver from stemness to expanded differentiation potential, while (ii) blocking reprogramming from somatic to stem cells (Pre-print and Salazar-Roa et al., 2020).
Accumulating evidence has shown that some cancer cells share certain biological and molecular properties with tissue-specific stem cells. Those observations are consistent with the idea that, for tumor initiation, adult cells are required to undergo reprogramming to a progenitor-like fate, suggesting that pluripotency and tumorigenesis entail obvious similar pathways.
Inspired by this general thought and supported by the AECC Scientific Foundation, we aim to develop novel strategies for anti-tumoral Advanced Differentiation Therapy, to directly confront the tumor-maintaining and regeneration capability of cancer cells.
We anticipate that our Differentiation Technology will drop the stem population in the tumor, in part by unlocking the cellular differentiation programs that are normally inactivated in cancer stem cells and at the same time, blocking the reprogramming from somatic to cancer stem cells.

Innovation and Tech transfer
The Cancer STEM Lab has a real commitment with transferability. Since 2019, we are proud to participate in prestigious Innovation programs, from Spain and US: our team and project were chosen, trough highly competitive selection processes, to be part of CaixaImpulse 2019 and MIT linQ IDEA2 Gobal 2019.
CaixaImpulse personalized training was developed during 2019 in Barcelona. This program has provided us funding to develop our “Proof of concept” and has offered us the tools we need to improve our valorisation and commercialisation plans.
MIT linQ face-to-face training was also developed during 2019, in Cambridge (Boston). Mentorship and personalized guidance are crucial in this program to efficiently refine our research plans and development strategy, in order to heighten the opportunity to healthcare impact. Our IDEA2 innovation training and individualized mentorship are being extremely helpful for us, to make the right decision in every step of this exciting process.
The Global CoCreation Program at MIT IMES is a high-tech concentrator launched by the MIT (Massachusetts Institute of technology) and sponsored by Miami-Dade County. We are proud to be part of this amazing initiative since 2020, invited by its CSO, Mercedes Balcells-Camps.
