Alkaptonuria (AKU) is a rare inborn error of metabolism caused by a defective homogentisate 1,2-dioxygenase (HGD), an enzyme involved in the tyrosine degradation pathway. Loss of HGD function leads to the accumulation of homogentisic acid (HGA) in connective body tissues in a process called

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that

The mammary-specific polyomavirus middle T antigen overexpression mouse model (MMTV-PyMT) is one of the most commonly used models in the cancer research field for multiple reasons, among which the spontaneous development of multifocal luminal tumors, the early tumoral onset, and the primary tumors'

The protocol is aimed at developing primary human breast organoids that have a morphology similar to the one observed in the in vivo breast. This morphology encompasses a complex network organization composed of interconnected branches that terminate in TDLU-like structures. The organoids are

The protocol is aimed at developing primary mammary gland organoids that have a morphology similar to the one of the in vivo breast, which is organized as a complex network of interconnected branches. The organoids are derived from the mouse mammary gland by mechanical dissociation and enzymatic

This method describes the generation of porcine testicular organoids using piglet testicular cells seeded in a testicular extracellular matrix (tECM) hydrogel. To generate the solublized tECM hydrogel, porcine immature testicular tissues (ITTs) were dissected in small fragments and decellularized in

E. coli is one of the organisms of choice for the production of recombinant proteins. DH5 alpha cells are commonly used for maintenance, propagation and mutation, whilst BL21(DE3) and C43(DE3) are mainly used for expression of the transgene. The advantage of C43(DE3) is that is used to produce

We have developed a protocol for culturing primary neuron progenitor cells (NPCs) derived from mouse embryos at embryonic day 15 (E15). These cells are highly proliferative, can be subcultured and cryopreserved and can be differentiated to neurons or astrocytes. Hence, this method can greatly reduce
