C stars in the outer spheroid of NGC 6822 [PDF]

, 2006
From a 2 x 2 degree survey of NGC 6822 we have previously established that this Local Group dwarf irregular galaxy possesses a huge spheroid having more than one degree in length.

Preparation of Spheroids from Primary Pig Cells in a Mid-Scale Bioreactor Retaining Their Myogenic Potential

Cells, 2022
Three-dimensional cell culture techniques mimic the in vivo cell environment more adequately than flat surfaces. Spheroids are multicellular aggregates and we aimed to produce scaffold-free spheroids of myogenic origin, called myospheres, using a mid ...

Focused Ultrasound Treatment of a Spheroid In Vitro Tumour Model

Cells, 2022
Focused ultrasound (FUS) is a non-invasive technique producing a variety of biological effects by either thermal or mechanical mechanisms of ultrasound interaction with the targeted tissue.

Intercellular Communication in Spheroids [PDF]

, 1984
This chapter has shown that the response of spheroid cells to gap junctional communication may lead to certain metabolic and cell physiological changes. It has also become apparent that the functions of the gap junctions are very complex. They may, for example, be related to the fundamental effects of cAMP and/or Ca 2+.

The Detailed Star Formation History in the Spheroid, Outer Disk, and Tidal Stream of the Andromeda Galaxy [PDF]

, 2006
Using the Advanced Camera for Surveys on the Hubble Space Telescope, we have obtained deep optical images reaching stars well below the oldest main sequence turnoff in the spheroid, tidal stream, and outer disk of the Andromeda Galaxy.

3D Cardiac Cell Culture: A Critical Review of Current Technologies and Applications

Frontiers in Cardiovascular Medicine, 2019
Three-dimensional (3D) cell culture is often mentioned in the context of regenerative medicine, for example, for the replacement of ischemic myocardium with tissue-engineered muscle constructs.

Characterization of the Anti-Cancer Activity of the Probiotic Bacterium Lactobacillus fermentum Using 2D vs. 3D Culture in Colorectal Cancer Cells

Biomolecules, 2019
The aim of this study was to investigate the potential anti-cancer effects of probiotic cell-free supernatant (CFS) treatment using Lactobacillus fermentum for colorectal cancer (CRC) in 3D culture systems.

Investigation of the aerodynamic characteristics of a lifting body in ground proximity [PDF]

, 2016
The use of cambered hull shapes in the next generation of lighter-than-air vehicles to enhance aerodynamic performance, together with optimized take-off manoeuvre profiles, will require a more detailed understanding of ground proximity effects for such

Engineering three-dimensional bone macro-tissues by guided fusion of cell spheroids

Frontiers in Endocrinology, 2023
IntroductionBioassembly techniques for the application of scaffold-free tissue engineering approaches have evolved in recent years toward producing larger tissue equivalents that structurally and functionally mimic native tissues.

Dwarf Spheroidal Galaxies [PDF]

Symposium - International Astronomical Union, 1994
Dwarf Spheroidal (dSph) galaxies are the faintest baryonic systems recognized as galaxies. Understanding the structure and stellar populations of these systems is critical for the modelling of their formation and evolution, and by extension, for understanding the general problem of galaxy formation ...
