Background: Human Wharton’s jelly mesenchymal stem cells (HWJMSCs) express liver-specific markers such as albumin, alpha-fetoprotein, cytokeratin-19, cytokeratin-18, and glucose-6-phosphatase. Therefore, they can be considered as a good source for cell replacement therapy for liver diseases. This study aimed to evaluate the effects of various culture systems on the hepatocyte-specific gene expr...

background: plants are among promising and suitable platform systems for production of recombinant biopharmaceutical proteins due to several features such as safety, no need for fermentation, inexpensive investment, and fast and easy scale-up. human insulin is one of the most widely used medicines in the world. up to now different expression systems including escherichia coli, yeast and cho hav...

introduction: the development of an effective vaccine against hepatitis c virus (hcv) is still a target of intensive vaccine research. the hcv envelope proteins e1 and e2 which can induce broadly neutralizing antibodies are the major candidate for this purpose. different types of expression systems have been used to express these glycoproteins. in this study, an expression system using pichia p...

introduction: human hematopoietic stem cells (hhscs) have been used for transplantation in hematologic failures. because the number of hhscs per cord blood unit is limited, the expansion of these cells is important for clinical application. it has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hhscs. in this regard, cord blood cd34+ cells expanded a...

Background: Follicle stimulating hormone is a heterodimeric protein composed of two subunits, α and ß, which are linked noncovalently. The hypophysial gonadotropin FSH plays an important role in the regulation of oocyte maturation, and a key component for growth of ovulator follicles in ewes. Materials and Methods: This study seeks to clone and express the ovine follicle stimulating hormone sub...

Molecular farming technology offers a unique advantage that almost any protein can be produced economically and safely under very controlled conditions. Besides traditional production systems, such as bacteria, yeasts, insects and mammal cell lines, plants can now be used to produce eukaryotic recombinant proteins, especially therapeutic ones. Their advantages as hosts for protein production in...
