The tumor associated stroma has been described in recent years as being complicit in tumor growth in pancreatic cancer. The stroma hosts a variety of components of both cellular and molecular makeup. In normal tissues, the stroma provides nutrients and regulatory signals for proper cellular polarity and function. However, following oncogenic transformation, the stromal compartment is conscripted to provide stimulatory signals and protection to tumor cells. It is these tumor-stromal interactions that are currently of great therapeutic interest. Several key reports have suggested that therapeutic targeting of the tumor-stromal interactions in pancreatic cancer has the potential to offer survival benefit. In this review, we will discuss the tumor-stromal interactions that contribute to tumor growth and progression, and ways in which we might counter these interactions.

Patient-centered precision oncology strives to deliver individualized cancer care. In lung cancer, preclinical models and technological innovations have become critical in advancing this approach. Preclinical models enable deeper insights into tumor biology and enhance the selection of appropriate systemic therapies across chemotherapy, targeted therapies, immunotherapies, antibody-drug conjugates, and emerging investigational treatments.

Gastric cancer (GC) is a major cause of global cancer mortality with high levels of heterogeneity. To explore geospatial interactions in tumor ecosystems, we integrated 2,138 spatial transcriptomic regions-of-interest (ROIs) with 152,423 single-cell expression profiles across 226 GC samples from 121 patients. We observed pervasive expression-based intratumor heterogeneity, recapitulating tumor progression through spatially localized and functionally ordered subgroups associated with specific immune microenvironments, checkpoint profiles, and genetic drivers such as SOX9.

Pancreatic cancer, especially pancreatic ductal adenocarcinoma (PDAC), is one of the most challenging clinical conditions due to its late-stage diagnosis and poor survival rates. Mesenchymal stem cells (MSCs), used for targeted therapies, are being explored as a promising treatment because of their tumor-homing properties and potential contributions to the pancreatic cancer microenvironment. Understanding these interactions is crucial for developing effective treatments.

Three-dimensional (3D) tumor models provide physiologically relevant tumor environments and have become a major tool in cancer research and drug discovery. This article presents a protocol for creating a 3D organotypic tumor model by embedding a cancer cell spheroid within a collagen matrix containing dispersed fibroblasts. This model offers significant advantages over the conventional monolayer cell culture, monoculture spheroids of cancer cells, and intermixed co-culture of cancer and stromal cells by mimicking the spatial organization and mechanical properties of a solid tumor.

Retinoblastoma (RB) is an intraocular tumor arising from retinal cone progenitor cells affecting young children. In the last couple of years, RB treatment evolved towards eye preserving therapies. Therefore, investigating intratumoral differences and the RB tumor microenvironment (TME), regulating tumorigenesis and metastasis, is crucial.
