(b) Hyaline cartilagineous tissue (×) and an ossification process of the cartilage (arrows). A bone trabecula is indicated by the asterisk with a close adipose tissue (hashtags).

(d) Hyaline cartilage is stained with blue and cartilage in red during the process of calcification. (e) Bone trabecula at higher magnification. Scale bar: a, b, d: 20 μm; c, e: 30 μm
