Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps. The fibroblasts within the granulation tissue develop into chondroblasts which also form hyaline cartilage. Microscopically, mucoceles appears as granulation tissue surrounding mucin. Pannus is an abnormal layer of fibrovascular tissue or granulation tissue. The extracellular matrix of granulation tissue is created and modified by fibroblasts. Both wet granulation and dry granulation (slugging and roll compaction) are used. HA is abundant in granulation tissue matrix. They are found typically in granulation tissue and stroma of tumours. Cell migration is essential for the formation of granulation tissue. Guar gum grading involves analysis for coloration, viscosity, moisture, granulation, protein content and insolubles ash. The clot is eventually lysed and replaced with granulation tissue and then later with collagen. Metalworking techniques included lost-wax casting, plating, filigree, and granulation. It may be sessile or pedunculated and is composed of fibrosed granulation tissue. Such techniques as filigree and granulation gradually disappeared. Photography assisted in the study of solar prominences, granulation and spectroscopy.
