Stromal cells of endometrium, also called endometrial stromal fibroblasts, are the connective tissue cells of the uterine lining that drive its monthly remodeling and, during pregnancy, differentiate into decidual cells essential for embryo implantation.
Stromal cell of thymus
Thymic stromal cells are the non-lymphocyte support cells of the thymus, including thymic epithelial cells, fibroblasts, endothelial cells, and pericytes, which build the microenvironment for T cell development, selection, tolerance, and age-related involution.

Stromboli
Stromboli, northernmost of the Aeolian Islands in the Tyrrhenian Sea, is a persistently active stratovolcano whose regular mild explosions define the Strombolian eruption type; paroxysms in 1919, 1930, 2003, and 2019 mark its hazards.
Stromboli (food)
Stromboli is an Italian-American baked turnover of pizza or bread dough filled with cheese, cured meats, and vegetables, credited to a Philadelphia pizzeria in the 1950s and named after the 1950 film Stromboli.
Stromelysin (MMP-3 and MMP-10)
Stromelysin is the name for two matrix metalloproteinase enzymes, stromelysin-1 (MMP-3) and stromelysin-2 (MMP-10), which degrade fibronectin, laminin, gelatins, and proteoglycans, and activate the pro-enzyme forms of other MMPs.
Stromme syndrome
Stromme syndrome (Strømme syndrome, OMIM 243605, CILD31) is a rare autosomal recessive ciliopathy caused by biallelic CENPF variants, combining microcephaly, apple-peel intestinal atresia, and ocular anomalies, first described in 1993.

Strong and weak typing
Strong and weak typing are informal labels with no universally agreed definitions, describing how strictly a programming language's type system restricts operations, and many educators prefer precise terms like type safety.

Strong column-weak beam is a seismic design principle requiring columns to be stronger than the beams at a joint, so beams yield first in earthquakes.
Strong coupling regime
The strong coupling regime is a condition of cavity quantum electrodynamics in which the coherent coupling between a quantum emitter and a cavity mode exceeds both loss rates, enabling reversible energy exchange.
Strong CP problem
The strong CP problem is the unexplained smallness of CP violation in quantum chromodynamics, where experiments constrain the parameter to at least ten orders of magnitude below its natural size.
