Flow Table Test01:12

Flow Table Test

The flow table test is an established method used to assess the workability of concrete, particularly useful for evaluating highly flowable concrete mixes. This test employs an apparatus that consists of a wooden board topped with a steel plate, collectively weighing 35 pounds. The board is connected to a base via a hinge and measures 27.6 inches on each side.
Concrete is placed within a truncated cone mold that is 8 inches high with an 8-inch base diameter and a 5-inch top diameter. The...
Flow Cytometry01:23

Flow Cytometry

The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Area of Science:

  • Biophysics
  • Cell Biology
  • Skeletal Physiology

Background:

  • Mechanical signals regulate skeletal homeostasis, influencing bone formation and loss.
  • Bone cells' perception of biophysical changes is poorly understood, but interstitial fluid flow is a key initiator.
  • Understanding cellular responses to mechanical stimuli is vital for skeletal health research.

Purpose of the Study:

  • To investigate the effects of fluid flow on bone cell behavior.
  • To elucidate the signaling cascades activated by interstitial fluid flow in bone cells.
  • To present novel in vitro systems for studying mechanotransduction in bone.

Main Methods:

  • Utilized a parallel plate flow chamber to stimulate single bone cell types.
  • Employed a rotating disk fluid flow apparatus for fluid flow experiments.
  • Used commercially-available cell culture inserts to model cell-cell communication under fluid flow.

Main Results:

  • Demonstrated the capability of the developed in vitro systems to apply controlled fluid flow to bone cells.
  • Provided a foundation for examining bone cell responses and downstream signaling pathways.
  • Enabled the study of how fluid flow influences bone cell communication.

Conclusions:

  • The presented in vitro systems are effective tools for studying bone cell mechanobiology.
  • Further research using these models can elucidate the mechanisms of skeletal adaptation to mechanical loading.
  • These systems will advance our understanding of skeletal homeostasis and bone disease.
