What's the difference between spherelike and spheroidal?

Spherelike


Definition:

Example Sentences:

  • (1) At low concentrations, the aggregates consist of only few cells forming spherelike particles displaying hemodynamic properties better than those of the single discoid cells.
  • (2) The RcRm complex is named Rs (s indicates spherelike).
  • (3) This complex consists of a spherelike, hollow head piece, in the wall of which a number of copies of the methyl coenzyme M methylreductase are located.

Spheroidal


Definition:

  • (a.) Having the form of a spheroid.

Example Sentences:

  • (1) Microelectrodes were used to measure the oxygen tension (PO2) profile within individual spheroids at different stages of growth.
  • (2) Aside from typical nuclear spheroids, irregularly shaped nuclei were frequently seen, associated with increased nuclear folds, transitional stages between nuclear folds and nuclear spheroids were also present.
  • (3) The nuclei in these typical onocytes appeared oval or spheroid.

  • (8) In addition, it was observed that the higher resistance of the V79 spheroid cells than the monolayers to gamma-irradiation is not diminished in the pion peak, suggesting that the underlying phenomenon of intercellular communication influences cell survival even after high-LET irradiation.
  • (9) Under the 3-dimensional geometry of the spheroid system, there was, however, generally a more extensive ECM.
  • (10) The spheroids grew exponentially with a volume-doubling time of approximately 24 h up to a diameter of approximately 580 microns and then the growth rate tapered off, more for spheroids grown at the low than at the high oxygen tension.
  • (11) The cytotoxicity of doxorubicin (DX), 4'-O-methyl-DX (MET-DX), 4'-deoxy DX (DEO-DX), 4'-deoxy-4'-iodo-DX (IODO-DX), daunorubicin (DNR)and 4-demethoxy-DNR (DM-DNR) on LoVo cells cultured as a monolayer (in exponential and stationary phases of growth) and as spheroids, are evaluated following 1-h exposure to the drugs.
  • (12) Under conditions of severe hypoxia (< 0.01% O2), 2 h of pretreatment or 18 h of simultaneous treatment with SR 4233 did not significantly enhance the effectiveness of 131I-NR-LU-10 in spheroids.

  • (18) Transplanted spheroids continued to express the growth inhibitory activity.
  • (19) The outer-layer cells of spheroids and fed plateau monolayers peaked at a similar density; the majority of middle-layer cells banded close to unfed plateau and exponential hypoxic monolayers, while most inner-layer cells banded where fed or unfed plateau hypoxic monolayer peaked in density.
  • (20) Survival of spheroid and monolayer cells after hypertonic NaCl treatment was identical.
