Knospe, Clemens; Böhme, G. (1995): Zur pränatalen Entwicklung der Glandula mandibularis und Glandula parotis der Katze. In: Anatomia, Histologia, Embryologia, Vol. 24, No. 1: pp. 1-6

The prenatal development of the cat's mandibular and parotid gland was examined by means of serial section of 36 cat embryos at 14–62 days of development. Both glands were excised from the epithelium of the primitive oral cavity and branched up to day 36 of the branching phase into a specific connective tissue. This tissue contained besides fine collagenous fibres, a high amount of proteoglycans. In the subsequent separation phase, ducts and acini differentiated themselves in primitive lobules which were separated by connective tissue. In the prenatal differentiation phase, from about day 50 up to birth, intercalated ducts and striated ducts were formed. In the acini, mucous and serous cells contained different amounts of complex carbohydrates. This secretory component changed shortly before birth.
