Fabrication of Three-Dimensional HepG2 Liver Tissue by Centrifugation

Tokyo Women's Medical University Journal
Background: We previously developed a rapid three-dimensional (3-D) tissue fabrication method using centrifugation. In this study, we fabricated 3-D HepG2 liver tissues using a scaffold-free centrifugation method and analyzed them biochemically. Methods:

Lateral Separation of Macromolecules and Polyelectrolytes in Microlithographic Arrays

, 1997
A new approach to separation of a variety of microscopic and mesoscopic objects in dilute solution is presented. The approach takes advantage of unique properties of a specially designed separation device (sieve), which can be readily built using already

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Standardization of Platelet-Rich Plasma Preparation in Orthopedics: A Review of the Literature and Proposal for a Reproducible Protocol

LabMed
Platelet-rich plasma (PRP) is widely used in orthopedics and sports medicine as an autologous product; however, substantial heterogeneity in manufacture and incomplete reporting of preparation parameters limits reproducibility and inter-study ...

Vimentin filaments are assembled from a soluble precursor in avian erythroid cells [PDF]

, 1983
The synthesis and assembly of vimentin was studied in erythroid cells from 10-d-old chicken embryos. After various periods of [35S]methionine incorporation, cells were lysed in a Triton X-100-containing buffer and separated into a soluble and an ...

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

The Infiltration-centrifugation Technique for Extraction of Apoplastic Fluid from Plant Leaves Using Phaseolus vulgaris as an Example

Journal of Visualized Experiments, 2014
The apoplast is a distinct extracellular compartment in plant tissues that lies outside the plasma membrane and includes the cell wall. The apoplastic compartment of plant leaves is the site of several important biological processes, including cell wall ...

Phase-separation of miscible liquids in a centrifuge [PDF]

, 2007
We show that a liquid mixture in the thermodynamically stable homogeneous phase can undergo a phase-separation transition when rotated at sufficiently high frequency $\omega$.
