Calmodulin (CaM) is a pivotal multifunction regulator of calcium metabolism in nearly all organisms, and earlier studies revealed its underlying involvement of shell or pearl formation in oysters. Culture pearls are formed within complete pearl sacs. However, whether CaM functions in pearl sac formation or not is not reported.

Pearl oyster Pinctada martensii is cultured for production of pearl in China. It needs to implant a mantle graft cut from a donor oyster and a seed nucleus into the gonad of the host oyster to produce a pearl. Pearl sac surrounding the nucleus is formed by the proliferation of the implanted mantle graft from the outer mantle epithelial cells in the ...

For pearl culture, the pearl oyster is forced open and a nucleus is implanted into the gonad with a mantle graft. The outer mantle epithelial cells of the implanted mantle graft elongate and surrounding the nucleus a pearl sac is formed. Shell matrix proteins secreted by the pearl sac play an important role in the regulation of pearl formation ...

In the process of production of freshwater pearl, implanted mantle pieces undergo a series of complex physiological and biochemical processes to form pearl sac, which produce pearl. This is a very important site of occurrence due to immune-induced biomineralization, while its molecular regulatory mechanism is still unclear.

Epidermal growth factor receptor (EGFR) plays an important role in cell growth, proliferation, differentiation and migration. Yet whether it functions in pearl formation or not is not reported. In this study, EGFR was cloned from the pearl oyster Pinctada fucata (named as Pf-EGFR) and its expression profiles were investigated.

Matrix proteins regulate crystal nucleation, morphology, and polymorphism during pearl biomineralization and have significant correlations with pearl quality traits in nucleated pearls. However, there is little information about the connection between pearl quality traits and matrix proteins in non-nucleated pearls.

Abstract In the pearl culture it is still unclear whether cells in mantle grafts from donors remain in the pearl sac and whether they contribute to nacre formation in Akoya pearl oyster (Pinctada fucata). In this study, we compared the nucleotide sequences of the polymorphic genes coding for two important matrix proteins N16 and N19 among the donor ...

Effects on the early development of the pearl sac by cytochrome c, yolk lecithin and polyvinyplyrro
Wuhan University Journal of Natural Sciences, 1997Mantle pieces ofHyriopisis cumingii was treated by three kinds of solution, These mantle pieces were inserted together with paraffin nucleuses into the connective tissue of three groups ofHyriopisis cumingii. These operated animals were cultured in a pool for a month.

Successful allograft of mantle tissues in certain bivalve mollusks can form pearl sacs secreting nacre for pearl production. Little was known, however, about the immune consequences in response to the tissue transplantation. In the present study, interleukin (IL)-17, one of the key regulatory genes of alloimmunity, was cloned from the triangle-shell ...
