The phrase "attached spheres" is correct and usable in written English.
It can be used in contexts where you are describing spheres that are physically or conceptually connected to something else.
Example: "The artist created a sculpture featuring attached spheres that symbolize unity and connection."
Alternatives: "connected spheres" or "joined spheres".
The removed core of the attached spheres could, like the first spheres, be used repeatedly (about twenty times) as seed for neural stem cells.
By culture of the spheres in NSCM, neural stem cells were able to migrate from the attached spheres to the surrounding area and subsequently form a circular cluster.
After removing the core of the attached spheres mechanically, the remaining neural stem cells could proliferate in NSCM and selectively differentiate into neurons and astrocytes by subculture in an appropriate medium.
The attached spheres were fixed in phosphate-buffered saline- (PBS-) buffered 4% paraformaldehyde and 2% sucrose, washed three times with PBS, permeabilized with 3% bovine serum albumin in PBS containing 0.3% Triton X-100, and blocked with 5% normal goat serum.
Adipogenesis was examined in nude mice injected subcutaneously with ADSCs (group I), PLGA spheres (group II), or ADSCs attached PLGA spheres (group III) cultured in adipogenic medium for 7 days.
The bacteria were attached constituting spheres and very minor maintenance operations were required.
In contrast, the effective optical thickness, which reflects the effective refractive index of the porous layer, was not influenced by the attached hydrogel spheres.
Whereas the FFT amplitude of the bare porous silicon film followed the changes in the refractive index of the surrounding medium, the FFT amplitude of the pSi/polyNIPAM structure depended on the swelling/shrinking of the attached hydrogel spheres and exhibited a minimum in ethanol-water mixtures with 20 wt% ethanol.
A coating of titanium dioxide (yellow spheres) attached to dye molecules (pink spheres) surrounds the bundle.
The target frame consisted of three large spheres attached to a stiff frame; sphere A was offset in the posterior-lateral direction, sphere C in the posteromedial direction and sphere B in the anterior direction relative to the implant reference point, as shown in Figure 1b.
The latter nano-chain was created by attaching two spheres of 30 nm on the solid support and conjugating 10 nm spheres onto the available amines on the sides of the chain.
