Treatment of primary mouse osteoblasts with retinoic acid produces a homogeneous population of ramified cells bearing morphological and molecular features of osteocytes. The method overcomes the difficulty of obtaining and maintaining primary osteocytes in culture, and can be advantageous to study cells derived from transgenic models.

Here, we present a protocol for the synthesis of CH₃NH₃I and CH₃NH₃Br precursors and the subsequent formation of pinhole-free, continuous CH₃NH₃PbI_3-xBr_x thin films for the application in high efficiency solar cells and other optoelectronic devices.

Evaluation of the Interplay Between the Complement Protein C1q and Hyaluronic Acid in Promoting Cell Adhesion

Romana Vidergar^*1, Chiara Agostinis^*2, Paola Zacchi¹, Alessandro Mangogna¹, Fleur Bossi², Fabrizio Zanconati³, Marco Confalonieri³, Giuseppe Ricci^2,3, Roberta Bulla¹

¹Department of Life Sciences, University of Trieste, ²Institute for Maternal and Child Health, IRCCS (Istituto di Ricovero e Cura a Carattere Scientifico) Burlo Garofolo, ³Department of Medical, Surgical and Health Science, University of Trieste

The complement component C1q is a pro-inflammatory molecule highly expressed in the tissue microenvironment that can interact with the extracellular matrix. Here, we describe a method to test how C1q bound to hyaluronic acid impacts cell adhesion.

Genetics

Generation of Cancer Cell Clones to Visualize Telomeric Repeat-containing RNA TERRA Expressed from a Single Telomere in Living Cells

Laura Avogaro¹, Claudio Oss Pegorar¹, Nicole Bettin^1,2, Emilio Cusanelli¹

¹Laboratory of Cell Biology and Molecular Genetics, Department of Cellular, Computational and Integrative Biology - CIBIO, University of Trento, ²Department of Life Sciences, University of Trieste

Here, we present a protocol to generate cancer cell clones containing a MS2 sequence tag at a single subtelomere. This approach, relying on the MS2-GFP system, enables visualization of the endogenous transcripts of telomeric repeat-containing RNA (TERRA) expressed from a single telomere in living cells.

Biology

Rat Liver Perfusion and Primary Hepatocytes Isolation: An Old Procedure Crucial for Cutting-Edge 3D Organoids Culture

Valentina Tiriticco¹, Gabriele Codotto^1,2, Benedetta Blarasin^1,2, Noel Salvoza^1,2, Marco Stebel², Claudio Tiribelli¹, Cristina Bellarosa¹

¹Italian Liver Foundation, ²Department of Life Sciences, University of Trieste

This protocol presents an optimized two-step collagenase liver perfusion technique in a rat model and shows the use of isolated hepatocytes for in vitro long-term culture of 3D organoids.
