Concept Design and optimization of cell culture processes requires intensive studies based on “Design of experiments”-strategies. In academia teaching of DoE-concepts is often insufficient, as in most cases only simple culture strategies (batch) can be performed, as time and money are limited. More complex tasks such as feeding strategies for fed batch culture can be discussed theoretically onl...
Many investigations have utilized techniques for culturing ovarian tissue or isolated follicles in vitro. Whole ovaries from fetal or neonatal rodents have been incubated in organ culture systems. This has been utilized to understand the sequence of follicle formation and its hormonal requirements, activation of quiescent follicles, follicular growth and development, and acquisition of steroido...
Aryl hydrocarbon hydroxylase activity in human placenta from cigarette smoking and nonsmoking women.
Microsomal aryl hydrocarbon hydroxylase 4 is known to be present and inducible by polycyclic hydrocarbons in a variety of tissues of many species in vivo (5, 6, 12, 38, 40-43), in explants of rat lung in organ culture (42), and in mammalian cell cultures (24, 25). 5,6 This enzyme system may be important in understanding carcinogenesis, drug action, and steroid metabolism (4, 10). Polycyclic hyd...
