Web9 mei 2024 · This was probably because the particle (about 40 microns) was too large to be engulfed by macrophages and because of its CaHA component, pre-existing naturally within the human body. This inherent quality may have prevented immune cell recognition within 1 month or at 1 month (“early stage”) which explains their lack of cell attachment.
