At the establishment of MacBrainResource in early 2017, we started populating collections 1 to 5 and making them easily and widely accessible to researchers around the world. To celebrate the 5th anniversary of MacBrainResouce in 2021, we are adding collections 6 and 7. At its introduction, collection 6 is already an impressive set of serially stained sections for different neuronal and non-neuronal markers. This collection includes several brains in which coronal series of sections ~1 mm apart are stained for: calbindin (CB), choline acetyltransferase (ChAT), calretinin (CR), ionized calcium binding adaptor molecule 1 (Iba1), Myelin basic protein (MBP), neuronal nuclear protein (NeuN), Nissl, neuropeptide Y (NPY), oligodendrocyte transcription factor 2 (Olig-2), parvalbumin (PV), neurofilament protein (SMI-32), somatostatin (SOM), tyrosine hydroxylase (TH) and other. Collection 7 consists of brain tissue blocks, most of them frozen and already tested for immunohistochemical viability. The hope is that these new collections grow over the years to include male and female specimens within different developmental age groups.
In the past, to test the viability of collection 1, Dr. Duque used [3H]-thymidine injections from decades ago to compare neuron labeling to BrdU injected more recently. He found substantial differences in the number and distribution of labeled cells, indicating that the random incorporation of BrdU into the genes of dividing cells makes the fate of postmitotic neurons more prone to unpredictable errors than the incorporation of the more natural DNA constituent nucleotide. Because the results of his work have wide implications for studies that use BrdU in cell- migration, placement, connectivity and survival they were highlighted by several journals and gave rise to an invited chapter in a technical book series. In addition, Dr. Duque’s work on the development of the subplate utilized more than 40 cases from Collection 1 and illustrated how novel and noteworthy studies can be conducted using MacBrainResource, without having to sacrifice a single additional animal. These studies, and those previous ones in the laboratory of Dr. Pasko Rakic, were pivotal for the creation of MacBrainResource. Newer studies include development of cortical convolutions and gliogenesis in the outer subventricular zone as well as neurogenesis in the thalamus.
The potential of Collections 2-5 has been highlighted in recent original studies and publications by Drs. Selemon, Morozov and colleagues. Before the creation of MacBrainResource, Collection 4 was extensively used by Dr. Selemon to investigate the effects of x-irradiation in development. Most recently it has been used to corroborate findings from a new automated tract tracing method applied to diffusion tensor imaging (DTI) data and to study the effects of fetal x-irradiation on the numbers of dopaminergic cells of the substantia nigra and ventral tegmental areas. Collection 5 is being used to investigate cannabinoid receptors in cerebral neural stem cells. Currently all collections are being used in de novo investigations and for the collection of preliminary data essential for new grant applications. These collections hold a wealth of unmined data for normative primate brain structure that has yet to be tapped, as well as data regarding the morphologic consequences of lesions including prenatal irradiation.
