3D reconstruction of skin and spatial mapping of immune cell density, vascular distance and effects of sun exposure and aging
<p>Mapping the human body at single cell resolution in three dimensions (3D) is an important step toward a “digital twin” model that digitizes organ structure and the dynamics of cell-cell interactions. Current approaches for 3D reconstruction of multiplexed serial sections are relatively cumbersome and not automated. We present a novel 3D reconstruction workflow for multiplexed sequential tissue sections: MATRICS-A (Multiplexed Image Three-D Reconstruction and Integrated Cell Spatial - Analysis). This combines a reproducible and streamlined method for two-dimensional (2D) cell segmentation and cell type classification, followed by 3D volume reconstruction. We also provide novel tools for 3D visualization of immune cell cluster density, cell-to-vasculature distance, and distance maps for cellular markers of UV damage/repair and proliferation to the skin surface. We used MATRICS-A to reconstruct 26 serial sections of fixed skin from 12 donors aged between 32-72 years. Samples were collected from six distinct anatomical regions with mild to marked sun exposure effects. Each tissue section was multiplexed with 18 fluorescently labeled antibodies covering 14 cell types in the epidermis and dermis. We demonstrate several new findings that are only possible in 3D, We present novel visualization of immune cell clusters and show that there are 10-70% more T cells (total) within 30 µm of a T helper cell in 3D vs 2D. Distances of cell markers of DNA damage (p53), DNA repair (DDB2) and proliferation (Ki67) to the skin surface were consistent across all ages/sun exposure. MATRICS-A provides a new powerful integrated open access approach to quantify 3D spatial cell relationships in healthy and aging organs and could be further extended to diseased organs. </p>
The Thorsberg trousers – 3D reconstruction
The Thorsberg bog rendered two pairs of trousers, of which the best preserved is reconstructed here (Archäologisches Landesmuseum Schleswig, inv. no. F.S. 3684). The cut of the trousers is carefully executed and fits to the human body well.The reconstruction was made by using the original cutting pattern. The garment was put on an avatar in Clo3D software, textured in Substance Painter and post-processed in 3dsMax. For further details see https://doi.org/10.1016/j.culher.2021.03.003 The authors of the reconstruction are Martijn A. Wijnhoven (VU University Amsterdam), Aleksei Moskvin & Mariia Moskvina (Saint Petersburg State University of Industrial Technologies and Design).

Armour from Carlingwark Loch: 3D reconstruction
The 3D model presents a digital reconstruction of solid and riveted rings of mail armour from Carlingwark Loch (The National Museum of Scotland, inv. no. X.DV 2 (1866), https://sketchfab.com/nationalmuseumsscotland). To create 3D models of the rings, we used polygonal modelling functions of Blender software. In order to record the relevant measurements of the mail rings, we used a list of parameters. This list includes 11 parameters for a riveted ring and four parameters for a solid ring. The accuracy of the digital replicas of the rings was 0.01 mm.
