De la Puente Lab
Primary Research Focus
The de la Puente Lab develops translational and physiologically relevant preclinical cancer models as tools to recapitulate tumor behavior ex vivo (“out of the living”) with an emphasis in cellular crosstalk, extracellular matrix remodeling, and spatial gradients. We focus on elucidating mechanisms driving chemoresistance and immune evasion in women’s cancer and further developing novel treatment strategies to mitigate their occurrence. Our long-term goal is to accelerate and directly translate our significant insights to aid women suffering from cancer.

Lab Projects and News

Engineering tumor cellular compartmentalization with tumor-on-a-chip
Tumors are compartmentalized encompassing a complex network of cellular and non-cellular components, including fibroblasts, imperfect vascularization, spatial heterogeneity in the distribution of nutrients, oxygen, and signaling molecules, and ECM remodeling, which collectively create a specialized niche supporting tumor growth. Unfortunately, there are key limitations with current preclinical models recapitulating these key cellular crosstalk and spatial organization. We have developed a multicompartmentalized microvascularized tumor-on-a-chip as a novel preclinical model that recapitulates those key components of the dynamic and compartmentalized tumors microenvironment to further evaluate their critical role in modulating drug resistance.

Patient-derived tumor models as avatars for personalized prediction of therapeutic efficacy
Despite significant improvements in research and development in the cancer field, oncology clinical trials have the highest failure rate (96.6%) compared with any other therapeutic area. There is a lack of suitable preclinical models that accurately represent tumor behavior ex vivo (“out of the living”). To better understand the role and the complexity of the tumor microenvironment in human tumors, we are developing patient-derived tumors models as avatars for personalized prediction of therapeutic efficacy. This personalized drug screening platform allows rapid prediction of therapeutic response in vitro, thereby ensuring drug efficacy for each patient.

Engineering immune-cancer crosstalk and physiologically relevant oxygen gradients and ECM remodeling
One of the major components of the tumor microenvironment is the extracellular matrix (ECM), which undergoes remodeling and contributes to immune evasion mechanisms. Low oxygen is a key regulator of ECM remodeling, however, little is known about the role of the hypoxia-induced ECM remodeling in immune evasion and response to immunotherapy. We use patient-derived 3D model quantitative research methods to gain insight into the recreation of the hypoxia-induced ECM remodeling and its role in immune evasion.

Reprogramming normal fibroblasts into cancer-associated fibroblast
Cancer-associated fibroblasts (CAFs) are key contributors to cancer progression and therapeutic resistance through dysregulation of the extracellular matrix (ECM). CAFs are a heterogenous population derived from different cell types through activation and reprogramming. Current studies rely on uncharacterized heterogenous primary CAFs or normal fibroblasts that fail to recapitulate CAF-like tumor behavior. Our lab has developed a translational based approach to reprogram normal fibroblasts into CAFs using conditioned media from cancer lines. Using these resources, further development of therapeutics that possess potentiality and specificity towards CAF/ECM-mediated chemoresistance in OC are further warranted.

Biomarkers for early detection of Ovarian Cancer
Ovarian Cancer (OC) is a deadly disease for women, known as the “silent killer” due to its few symptoms and resistance to treatment that causes disease recurrence in more than three-quarters of patients. To date there is no approved biomarker for screening of OC or clearly identified drives of tumor recurrence. Our recent studies have identified new biological makers as potential candidate biomarkers for OC and key drivers of treatment resistance. Our goal is to develop a non-invasive blood test capable of detection of OC and further characterize the biomarkers’ implication in drug resistance. These studies have the potential to lead to biomarker tests able to detect OC early and develop treatment options for OC, capable of improving chemotherapy efficacy, preventing tumor recurrence, and thus improving patient survival.
