1. A small, often distinctive environment: microenvironments of the forest floor.
2. The area directly surrounding an organism or part of an organism, especially when it differs from the larger environment: the tumor microenvironment.
3. The immediate conditions or circumstances: a company's microenvironment.

Our new technique allows us to study changes to cells in the tumour microenvironment with unprecedented precision,' lead author Dr Ilaria Malanchi said.
(Paris: ALNOX) (Euronext Growth Paris: ALNOX), a biotechnology company focused on improving cancer treatments by targeting the tumor microenvironment (TME), announced today that following discussions with investors it has received letters of intent and binding commitments for long-term investment of EUR1 million through a private placement plus additional commitment for a future private placement.
NanoString Technologies announced the publication of a study in the journal Acta Neuropathologica that demonstrates the capability of the GeoMx Digital Spatial Profiler, or DSP, to characterize the microenvironment surrounding beta-Amyloid plaques in the brains of Alzheimer's disease, or AD, patients.
Providing operators with direct insights into their own environmental conditions as a way to reduce fatigue and prevent errors, the ABB Ability control room monitoring system supports the creation of a microenvironment that adapts to each individual's needs.
This rogue organ is known as the tumour microenvironment and is usually abundant in inflammatory cells and molecules.
This project aims to incorporate both in vivo and ex vivo models of cancer to explore the interactions between TAMs and MSCs in the tumour microenvironment. Both MSCs and TAMs have very specific signatures of gene expression in the tumour microenvironment, these will be resolved using microarray analysis in the polyoma middle T antigen (PyMT) mouse mammary tumour virus (MMTV) spontaneous model of breast cancer.
The joint research team also demonstrated that E7130 is not only a novel microtubule dynamics inhibitor but can also increase intratumoral CD31-positive endothelial cells (vascular remodeling activity) and reduce alpha-SMA (smooth muscle actin)-positive cancer-associated fibroblasts (anti-CAF effect), which are important constituents of the tumor microenvironment and may be involved in the malignant transformation of cancers in nonclinical in vivo studies.
TMAC - tumour microenvironment activated drug conjugates - is a new form of cancer immunotheraphy combining affimers with chemotherapies in a single drug using a linker designed to only release the chemotherapy in the tumour microenvironment, Avacta explained.
'We were able to show that glioblastoma cells react flexibly to such stress factors and simply transform themselves at any time into cell types with a different set of surface markers.' This plasticity allows the cells to adapt to their microenvironment and reach a favorable environment-specific heterogeneity that enables them to sustain and grow, and mostly likely to escape also therapeutic attacks.
receptor to overcome the suppressive tumor microenvironment. T cells are a critical part of the body's immune system that play a central role in fighting virus infections and cancers.
The ATP-adenosine, a key immune regulatory switch in the tumor microenvironment (TME) controls the inflammatory and suppressive activities of immune cells.
"We believe this shows that MSCs have durable action on colon cancer development by modulating the immune component of the tumor microenvironment," Annette Larsen said.
