However, only few studies have been conducted to assess and validate its prognostic value in laryngeal squamous cell carcinoma; none of which used pancytokeratin immunohistochemistry. In view of the modest results of treatment of laryngeal squamous cell carcinoma, the need of new prognostic indicators becomes of paramount importance. . We aim to evaluate tumor budding in laryngeal squamous cell carcinoma, by haematoxylin and eosin, as well as by pancytokeratin immunohistochemistry. . A retrospective study on 118 cases of laryngeal squamous cell carcinoma from archives of Pathology Lab of Ain Shams University Specialized Hospital and Ain Shams University Hospitals from January 2014 to January 2017. The ENT and histopathology reports were reviewed to determine clinicopathologic data of the patients. Tumor budding shows high statistically significant relations ( = 0.0001 for each) with important clinicte tumor budding in laryngeal squamous cell carcinoma especially in confusing cases.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent responsible for the development of a new coronavirus disease (COVID-19), is a highly transmittable virus which, in just ten months, infected more than 40 million people in 214 countries worldwide. After inhalation, aerosols containing SARS-CoV-2 penetrate to the depths of the lungs and cause severe pneumonia, alveolar injury, and life-threatening acute respiratory distress syndrome (ARDS). Since there are no specific drugs or vaccines available to cure or prevent COVID-19 infection and COVID-19-related ARDS, a new therapeutic agent which will support oxygen supply and, at the same time, efficiently alleviate SARS-CoV-2-induced lung inflammation is urgently needed. Due to their potent immuno- and angiomodulatory characteristics, mesenchymal stem cells (MSCs
